Renewable energy sources may be a hot topic in today’s environment but the concept is far from new. Some forms of renewable energy have been practiced for centuries. From the moment the first caveman rubbed two sticks together to start a fire, renewable energy was being used to provide heat or cook food. The sun, long before it was recognized as an engine to produce solar power, was quietly doing its job of warming the earth and producing light.

Two main factors are the driving forces in the development of renewable energy sources. First of all, renewable energy sources such as solar power or wind power are environmentally friendly as they do not emit greenhouse gases. Equally as important, renewable energy sources are just that, renewable. They cannot be depleted in the same way as natural gas, coal or oil supplies.

What exactly constitutes a renewable energy source? There are five main types.

1) One of the oldest forms of renewable energy is what is known as biomass energy. This form of energy is created from organic materials, such as when wood is burned to create heat. Today’s technology makes it possible to use plants, agricultural residue or even the organic remains from industrial waste as biomass to create energy. Common products being tested and marketed include new formulations of gasoline for automobiles being produced from corn, burning biomass to generate electricity and using biomass in products traditionally produced from petroleum.

2) Solar energy in its raw state has been around since the dawn of time. It is estimated that every hour of sunlight on the earth produces enough solar energy to accommodate the energy needs of the planet for an entire year. Harnessing that energy is the key to energy sufficiency in the future. Solar panels are becoming more common in industry and homes as heating solutions. On a larger scale, power plants make use of solar energy to generate electricity.

3) Wind has been used to power windmills used to grind grain or channel water long before the use of wind power was thought of as a renewable energy source in other areas of society. Windmill farms are becoming a booming industry. Wind turbines are used to capture the wind and turn it into electricity to support homes and businesses. Wind is a near perfect source of renewable energy. It is pollution free and, once the turbines used to harness its power are in place, the wind itself is free of charge.

4) Geothermal energy is a renewable energy option generated by heat beneath the surface of the earth. There are some limitations on its use as it is found in hot springs, geysers or volcanoes, sources not universally available. Power stations that supply geothermal energy must be located in areas where these geological features already exist. The energy is acquired through geothermal springs and is perpetually renewed by rainfall to restore the water supply that is heated beneath the earth’s surface. Despite the geological limitations of geothermal energy, the world resource supply has been estimated to be greater than the supply of coal, gas, oil and uranium combined.

5) Hydroelectricity is energy supplied by moving water. This energy source is another one that has been in use for centuries. Early farmers created water wheels to grind grain or irrigate crops. As far back as the late nineteenth century hydropower was harnessed to power the street lamps in Niagara Falls. Today, hydropower is the cheapest method of generating electricity. Once the hydro plants are in place and operational, the water, which is the source of energy, is free. Like the wind, it is replenished by nature on a steady basis.

Renewable energy sources are increasingly critical topics in today’s society. We can no longer rely on the depleting natural resources of gas, coal or oil to carry us through into the next century. These resources will not be naturally replenished and, because of their relative scarcity, they are often used as political control issues by countries with plentiful supplies in their dealings with countries that need those resources. Renewable energy options will provide the answers to future energy needs.

A typical stand-alone system consists of solar panels and or a small wind turbine to generate electricity connected to a charge controller which controls the pace at which batteries are recharged which is connected the battery bank. You will then need an off-grid inverter to convert the DC (Direct Current) electricity stored in the battery bank to AC (Alternating Current) electricity which is more commonly used in home appliances.

Years ago the high cost and poor reliability of early off-grid systems discouraged many except for the hardiest pioneers. Today solar, wind and hybrid systems have become so main stream that even families well within the utility power line reach are choosing to go off the grid.

At Blue Pacific Solar we believe that with the improvements in modern off-grid inverters, energy efficient lighting, propane and DC appliances, cheap price of quality solar panels and careful design considerations means stand-alone systems need not rely on backup fossil fuel generators.

The starting point in planning your system is to first reduce demand. Click on this link Off-Grid then click on the tab “Living Energy Conservation” for some tips.) Most people in America can easily cut their electricity consumption in half. Reducing your family’s energy consumption by conserving and investing in watt saving home lights and efficient appliances means you are putting your money in your pocket and can substantially reduce the amount of off-grid equipment and or battery bank. As you begin your journey towards freedom from the grid, start by conserving as much as possible first. Its always cheaper to save electricity than to generate electricity. Most off-grid generation is used for lighting, appliances like refrigerators and water pumping. Lighting is the easiest to tackle. Don’t stop at compact florescent lights, go all the way to LED which can use 1/6th the watt consumption of compact florescent lighting.

Here are some questions your will need to answer to get started choosing the right off-grid system for you:

• List your loads. How many watts per day do you expect your equipment to consume? The most important challenge in an off-gridsystem is to balance your energy consumption with your solar or wind turbine energy supply.  TIP: No easy way around this so get out a pencil and start listing everything you want to run and how long you usually run it. IE: 5 – 13 watt light bulbs X 5 hours per day = 65 watts. THIS IS IMPORTANT: When we say “list your loads”, we mean all your loads from the cell phone chargers to a hair dryer. How many days without sun or wind do you want to be able to run? (Days of Autonomy)
• What is the largest load you expect to run (Watts / Amps / Volts IE: 240V Well Pump @ 9.5 Amps)
• What is your budget?

TIP; The use of energy-efficient appliances and lighting, as well as non-electric alternatives such as a propane stove and refrigerator should be considered first. Every watt you save will help to lower the cost of your off-grid system.

With a little head scratching you can save yourself thousands of dollars by only purchasing the off-grid solar electric system you need without over purchasing.

Revised 5/6/2013 - It’s not all that hard to imagine a facility of the U.S. Forest Service (USFS) generating all of its own grid tied power from solar panels. After all, the USFS has a whole lot of facilities in the back of beyond, from offices to outhouses, that are well away from the benefits of civilization and electrical transmission. But the Forest Service’s announcement today that one of its facilities is now power-self-reliant with grid tied solar panels is a little unusual: That facility is in the middle of the suburban San Gabriel Valley.

As of September the USFS’s San Dimas Technology Development Center will be powered entirely by grid tied solar panels set up on one and a half acres of the grounds. The site’s 1,288 new solar panels will not only generate enough electricity to run the San Dimas center, but will sell enough extra power to help offset electric bills at the Angeles National Forest Supervisor’s Office in Arcadia.

The panels were installed with the help of a little over $1 million in stimulus funding, and will save considerably more than that over the lifetime of the project about $100,000 each year in avoided electric bills. In addition, the USFS embarked on an aggressive energy conservation plan at the facility with the help of California Conservation Corps workers, including weatherizing buildings, upgrading air conditioning and lighting, and installing occupancy sensors in rooms.

“This grid tied solar system has made the San Dimas Center a ‘net-zero energy’ facility, the first in the U.S. Department of Agriculture,” explained Forest Service Chief Tom Tidwell in a blog post on the USDA site. The Forest Service is overseen by the Department of Agriculture.

The San Dimas Center, founded in Arcadia in the 1940s as a firefighting technology study center, now hosts research on scientific aspects of National Forest land management from firefighters’ safety to engineering codes for scenic highways to advances in bearproof trash container technology. The Center moved to its current 18-acre site in 1965.

Modern battery-based off-grid solar systems offer more than just a DC-to-AC power source, they can charge batteries, select from multiple power sources, and control external functions. Here are a handful of steps you will need to take to plan for your off-grid purchase.

Appliance & Equipment Load List: List and add up your daily electrical equipment load demand in watt hours (wh):

Watt hours (wh) and amp-hours (aH); Watts = Amps X Volts. Watt hours are the most common measure of electricity usage and are the easiest to understand. Amp Hours = Watt hours / System Voltage. Many professional system designers will use amp hours to size a system because amp hours takes into account real world behavior of solar panels and battery banks. Either method will arrive at the same conclusion if done properly. For our purposes here, we will primarily use watt hours (wh) when sizing the number of solar panels (and inverter) and amp hours (aH) for our battery selection.

Energy Load Worksheet

TIP; What’s the difference between watts and watt hours? A watt = one joule “per second” and is a measurement of the rate of power flowing. 1 watt is a unit of energy equal to the power of one watt operating for one hour (3,600 joule’s). Watt and watt hours are often interchanged and misused. 1 watt hour (wh) = 1 watt of power supplied for 1 hour. Think of watts (w) as the speed you’re running and watt-hours (wh) as the distance you ran. A light bulb rated at 20 watts, in 1 hour it will consume 20 wh, and in 5 hours it will consume 100 wh.
System Voltage:

Higher voltage means less resistance which allows equipment to run cooler. Cooler electrical equipment = longer life.

Your system voltage means the nominal voltage you select for your battery bank, charge controller and inverter (if you are planning to use one). Here are some things to consider when choosing your systems voltage:

The DC system voltage is established by the battery bank in off-grid systems. A major factor in making this decision is how much power will be required from the batteries. As power demands increase it is advisable to raise the battery voltage. This voltage is important because establishes the type of charge controller and inverter that will be selected. The selection of the battery bank voltage affects the currents. A 1200 watt off-grid system operating at 12 volts draws 100 amps. (1200w / 12v = 100A). The same system draws only 25A at 48 volts. Lower amps reduces the size of conductors, over current protection devices, disconnects and charge controllers. Additionally, since voltage drop and power losses are smaller at lower amps, higher voltage off-grid systems are more efficient. As a rule of thumb, off-grid systems up to 1000 watts use a minimum 12 volt battery bank which limits DC currents to less than 84 amps. For 2000 watt systems, 24 volt battery banks are used. For 5000 watt system a 48 volt battery bank should be selected.

TIP; How long each day does a refrigerator run? 120VAC Refrigerators can be a large load for off-grid systems or they can be no draw. How often a refrigerator will run during a 24 hour day depends on many factors and will vary from home to home for the same refrigerator. Some of the variables include; the room temperature throughout the day, how full your refrigerator is (Full refrigerators run less often once the contents are cooled), and how often you open the door throughout the day. You can lower the run time of your refrigerator by turning off the automatic defrost function and keeping your refrigerator full. One off the grid living trick is to keep full jugs of water in a 1/2 full refrigerator which can help. Once the contents of the refrigerator are cooled, an energy efficient model in your home that is full might be expected to run 24% – 35% of the time with a room temperature of 70 degrees or about 6 hours out of 24.

Daily Off-grid System Charge Requirement in Amp Hours:

Since the energy output to the loads must be balanced by the energy input from your solar panels and or wind turbine, we need to calculate your daily charge requirement in amp hours as that number will come in handy later. Take your total daily what hours x 20% (rule of thumb) to account for losses in inverter, circuits and wire transfer. Now divide by the system voltage you chose based on the previous section and write this number down. This is the charge in amp hours your solar panels will have to provide each day to meet your load requirements you have set. Example 5,000 watts daily load total X 20% = 6,000 watts / 48 volt system = 125 amp hours that will need to be generated. If you follow those steps, you are on your way to putting some bling in your off-grid system and enjoying the zen it can bring.

Since home solar became a commercial option some 40 years ago central inverters have ruled the industry. Today about 40 percent of the home solar kit market is made up of Microinverter kits. A inverter is an electronic device that converters the direct current produced by solar panels to alternating current which is the electricity you use to run your home appliances and lights.

A grid tied inverter or utility inverters converts the DC current from the solar panels into AC current then syncs the sine wave to replicate the wave form provided by your utility company. To the extent that the solar panels produce more electricity than the home requires, excess electricity is pushed backed by the inverter to the public utility grid where the utility grid purchases or credits the homeowner for the power produced.

Grid tied solar panel systems use the local utility company power as a storage bank drawing from the utility company when necessary and pushing power back to the grid when the demand from the home is low. In the past sizing inverters meant the homeowner interested in installing their own solar panel kit would usually have to enlist the services of a local solar company due to the complexity of the system and the opportunities for poor performance due to engineering issues.

Those design hazards are no longer such an issue thanks in part to the advent of microinverters which are now sold in most DIY solar panel kits. Microinverters are small electronic devices that connect to or under a single solar panel rather than to a group of panels. Solar installers like these inverters because their ability to turn the individual solar panel to AC electricity while minimizing issues such as shading. Microinverters are typically less than 250 watts and are more commonly 235 watts. The main reason is the limitations of the individual microinverters but that appears to be slowly changing. Home solar kits are usually sized according the average monthly usage of the homeowners. The size of the system you choose depends on the amount of power you require (Watts), and the available solar insolation in your area. Take your last 12 month utility bills kWh, for each month, total the 12 months worth then div by 365 days. Next look at the solar insolation level for your area (average sun hours) and divide your daily average by the average amount of sun. That total will give you the approximate size solar kit you need to offset your utility bill.

To increase the efficiency of inverters for solar panel kits the majority of grid tied inverters use a single maximum power point tracker. A MPPT means if you have a combination of solar panels that needs multiple orientations you will need an inverter system that can track the maximum power point of the different arrays facing different directions. What that means if you have say two strings of solar panels on a house facing two different directions or different angles. The power curve of the two strings are also going to be different because the two strings of solar panels are not receiving the same amount of sunlight.

If you use a central inverter that has only one MPPT, the inverter will not be able to lock into the best MPPT for the complete solar system. Microinverters have made huge strides to minimize that issue because each invididual solar panel has it own microinverters hence its own MPPT tracker. Microinverter systems are now an integrated platform for increasing the productivity and reliability of home solar kits. The combination of solar panels and a microinverter makes it much easier to maximize the solar harvest of the home kit. Home solar kits are now more efficient than ever with a high degree of safety. Solar design and installation has been made simple thanks to the new technology of microinverters.

There is a lot of hype by solar panel manufactures about how more efficient their solar panels are over competion. That may be true by the numbers in many cases all other things being even, but solar panel efficiency is actually of little practical importance. Solar panels with lower efficiencies will simply have to cover a greater area which is usually not a problem except for those applications with limited space.

Recently I compared a leading solar panel company’s 235 watt 18% efficient panel against a competitor with a 235 watt solar panel that was 15.6% efficient. It was a substantial project with 108 panels. Both panels were compared with identical orientation, angle and using the same zip code. The 18% solar panel did out perform the 15.6% panel yes that’s true. But the performance difference amount to about 650 kWh per year. Now that may sound like a substantial increase in power but lets not forget the most important part of that comparison which is cost. The 18% efficient module’s cost was about 3X that of the 15.6% panels cost. That number is HUGE! compare to the 3% efficiency pick up.

In terms of dollars, it cost nearly $800 for the 18% efficient solar panel as compared to $341 for the 235 watt panel at 15.6%. Considering the payback the decision to go with the cheaper panel was far a better choice since there was no restrictions on space in this application.

System cost is expressed in terms of the energy yield of the panels that make up the solar system over a period of time, typically 25 years. Lower efficiency simply means that an array consisting of lower efficiency will have a larger surface area. The cost of the solar panels is the true variable in this equation that will increase the return on investment. When searching for the right solar panel for your project you may want to look closer at this factor.

As with any new technology and when big corporations feel they are threatened they put up resistance. Problem is big corporations control Washington DC. Solar panel feed-in-tariffs are going to be the next big thing in this country. It is small business start ups and local governments though that cut the widest swath to success. In America Florida, Sacramento, California, and Palo Alto, California are saying we can’t wait and are pushing forward past the Feds.

Palo Alto California is calling its solar panel program a CLEAN program (Clean Local Energy Accessible Now) rather than what they considered the awkward term “Feed-in Tariff” or FIT.

It’s a pilot program for the City of Palo Alto Utilities the first year is capped at 4 megawatts and meant for medium-sized commercial rooftops with a minimum size of 50 kilowatts per installation. The FIT is applicable to solar panel only technology, although other renewable energy sources could be considered later on. The city will pay $0.14 per kilowatt-hour for 20-year contracts.

Palo Alto is arguably the heart of Silicon Valley, home to dozens of venture capital firms and thousands of new companies, and armed with a startup and innovation-friendly culture fueled by its immediate neighbor, Stanford University. The city itself has about 26,000 electric meters and a peak load of approximately 180 megawatts.

The program limits itself to medium and large commercial solar rooftops in the interest of keeping workload issues to a minimum in the early stages of this solar panel program.

The $0.14 per kilowatt-hour figure was based on the city’s avoided cost. Here’s the calculation:

$0.070 for energy
$0.034 green premium
$0.006 local capacity value, essentially avoided distribution grid costs
$0.019 avoided transmission access charges (TAC), an amount paid in California for every kilowatt-hour that is delivered from the transmission grid.
$0.006 avoided transmission losses
Total: $0.1355 per kilowatt-hour

So, the $0.14 per kilowatt-hour FIT price includes a $0.0045 premium and was agreed upon as a number that would attract developer interest. The cost of a fully subscribed program would be $29,000 per year; the city council estimates that the cost to the utility customer would be $0.01 per month. At this scale and modest cost, the city gains experience with the permitting, interconnection, metering, and billing process while developers gain experience in working with Palo Alto.

Craig Lewis, the Director of the Clean Coalition, a distributed generation advocacy group, attended the February 7 Palo Alto City Council meeting and commented that he saw this as “a good program, because it is constrained and not open to residential rooftops.” He added, “It delivers the trifecta of being cost-effective, timely, and environmentally sustainable, and the solar panel pilot program is designed for success by avoiding pitfalls like dealing with tax complications of residential-level projects.”

Jon Abendschein, Palo Alto’s Resource Planner, believes that $0.14 per kilowatt-hour is a price that will attract developers to the program.

Lewis added, “There are dozens of places around the United States developing the bling needed for CLEAN programs, and Palo Alto just set the stage for this critical movement to unleash Clean Local Energy Accessible Now.”

Detractors of feed-in tariffs have claimed that the prices can never be set at a proper rate and that auction mechanisms are a more equitable solution. Others have argued that having no solar panel subsidy at all is the right solution.

The Midnite Solar Classic 150 MPPT battery charge controller substantially increases the flexibility, features and range currently found on all other MPPT controllers. The Midnite Solar Classic is the only MPPT controller that has arc fault detection, making this solar controller the safest controller available and a Hyper VOC feature. The solar consultants at Blue Pacific Solar love specifying Midnite solar products, well frankly because they are American Made, are designed for the most durable off-grid conditions and they work. With the Classic 150 ranging up to 96 amps, the Classic 200, 79 amps and the Classic 250, 63 amps, why would you need any other controller?

When sizing a MPPT battery charge controller a good rule of thumb is to take the total solar system’s short circuit current times a safety factor of 1.5 then select the current rating of the MPPT charge controller. Midnite solar has a unique feature called Hyper VOV. Hyper VOC refers to when the DC input voltage raises above the maximum operating voltage (150V, 200V, 250V, depending on the Midnite Solar Classic model). Hyper VOC gives you the flexibility to go up to the maximum operating voltage plus the nominal battery voltage. For example, the Midnite Solar Classic 150 solar battery charge controller has an input voltage rating of 150 operating volts, if the Classic 150 is connected to a 48 volt battery bank, the Hyper VOC voltage limit will be: 150V + 48V a total of 198 Volts that the Classic can withstand without breaking. When the Classic input voltage rises above 150 volts it will switch off (stop outputting power). As long as the Classic is in Hyper VOC mode, the microprocessor and all other functions like AUX will continue running. When the input voltage comes back down below 150v (or the rated operating voltage of the Midnite Solar Classic, depending on model) the Classic will wake up and start charging again automatically. This could happen in a really cold morning with a system that has a voltage open circuit (VOC) close to the maximum operating input voltage. When the Midnite Solar charge controller is in Hyper VOC mode, A Hyper VOC message will be displayed on the bottom right side of the status screen.

Midnite Solar Classic 150 charge controllers is a solid-state electronic device that, when sized properly, can be used in nearly every solar and wind energy system that uses batteries. The Charge controllers Blue Pacific Solar sells employ the latest in power electronics to regulate the battery charge by controlling the charging voltage and current from a solar panel array. Charge controllers regulate the charge of the battery, but also prevent the battery from being over discharged which can damage the battery bank.

Midnite Solar Classic 150 charge controller uses multiple stages of control to regulate different voltage and current levels. The voltage and current of a battery varies over the different stages of battery charge. Though the amount can vary, the bulk charge usually is approximately 80%, the absorption charge is 10% with the float charge representing the balance of the battery charging process.

The bulk charging stage of the Midnite Solar Classic 150 charge controller process is the first stage to used to bring the battery depth of discharge (DOD) back to 100%. The bulk charge stage happens first in in the morning after the batteries DOD has drained down since sunset the previous day. The bulk charging stage pushes as many amps into the battery bank as possible from the solar panels and gets the voltage up in the process. The effect of a charge controller is not unlike trying to fill a glass of water from a faucet. You first turn the faucet on full while the glass if filling, then slowly taper off the pressure until the glass is full. When the battery bank reaches a predetermined level known as the bulk voltage set-point, the charge is then substantially slowed. Because the bulk voltage set point is determined by the type of battery you are using, many charge controllers have to be pre-set to the type of battery which will dictate the rate of charge.

The second state of charge the Midnite Solar Classic 150 charge controller employs is the absorption stage. After a battery system has been brought up to the bulk voltage set point, the charge controller slows down the charge rate because the battery bank cannot accept the same rapid charging pace without overheating and damaging the battery bank. At the absorption stage a battery bank is only about 80% full. The absorption charge is the function level in the process that tops off the battery bank. During the absorption stage, the charge controller holds the battery volts constant and reduces the amount of current sent into the battery. When the absorption stage is complete, the battery bank is fully charges.

The final step the Midnite Solar Classic 150 charge controller performs is the float charge. Typically a charge controller enters into a float charge state when the other charge levels of the battery bank has been achieved. When the number of peak sun hours is limited, a solar charge controller may not be able to get the battery bank back to the float stage before the next cycle begins. Before installing any charge controller please read all the operator installation and safety instructions.
