Solar Electric Array

Imagine, freedom from your utility company! With Solar electric from GREENLOGIC, you can control the future of your electric bill. And, you'll have the power to create clean natural energy generating absolutely no pollution. Solar energy can be used in many ways - to provide heat, lighting, mechanical power and electricity.

Spin your electric meter backwards: Reduce or even eliminate your utility bill.

Natural, clean electricity: With solar power systems, you're generating no pollution or global warming. (Annually, a 5 kW PV system for an average size home, prevents 9,000 lbs. of coal from being mined, prevents 18,000 lbs. of CO2 from entering the atmosphere, keeps 6,300 gallons of water from being consumed, and keeps sulfur dioxide, nitrous oxide, mercury, and other pollutants from being released into the environment.

30 years! That's the expected lifetime of your solar panels.

Rebates & tax credits: tax credits, utility rebates and Renewable Energy Credits pay for up to 60%-80% of the system.

Reduce America's dependence on foreign oil: Americans consume 26% of the world's energy even though we only make up 5% of the world's population.


How you get electricity now: Electrical power from your utility flows from the electric grid into your home or business through a meter. The meter measures how much electricity you consume for billing purposes.

Solar panels produce electricity: Electricity is produced from sunlight using what are known as photovoltaic cells. These cells are built into thin glass-like panels of silicon material that produce electricity when exposed to sunlight. (They're similar in size to skylights.) The more intense the light and the more frequent, the more power you create. Even under cloudy conditions electricity can be produced although in lesser quantities. Solar Panel systems are extremely reliable with no moving parts and typically last 30+ years with no maintenance.

Converting power: The electricity that the solar panels produce can either be directly used in your building/structure or sent back to the utility for credit, or placed into storage batteries for later use. To accomplish this, the power coming off the panels goes through a device called an inverter (a box the size of a small cabinet mounted near your electric panel.) The inverter monitors the solar power system, conditions the power, and keeps track of how much electricity is produced and then feeds the power to the appropriate place.

Using the solar electricity you have generated: As you need electricity, it is drawn first from the solar power system. If you need more electricity than the system is generating, it is seamlessly supplemented with power from the utility connection. If you have a battery backup feature on your solar system, it will kick in during a power outage.

Your meter turns backwards & saves you money: Electrical power from your utility flows from the electric grid into your home or business through a meter. The meter measures how much electricity you consume for billing purposes.



What methods exist for capturing solar energy?

1. Solar electric (PV) You can turn sunlight into electricity to supplement and/or replace the electricity you buy from the local utility. This is done using solar photovoltaic (PV) panels that typically go on your roof or on towers or racks mounted on the ground.

2. Solar thermal/heating: The sun's heat can be captured and used to heat domestic hot water, pool water and even your home. This is done by using what are called solar thermal panels.

3. Passive solar: Finally, you can use specialized designs for your house that will allow the sun to enter your house in the winter and prevent the sun from coming in during the summer. These architectural designs are referred to as passive solar homes. They are typically designed with large south facing windows, and dense materials for the floors that capture the sun's heat. These passive solar designs also typically include overhangs that hide the southern windows from the summer sun thus block the solar heat from entering the structure.

Which kind of solar energy solution is right for me?

In the best of all worlds, you would use a combination of all of the solar solutions to maximize the benefits of each of them. This strategy works well for new construction or when you are doing major work on your property. If you are not doing new construction or major renovation you should focus on solar electric and solar heating/thermal. Your ability to use both of these methods will likely be constrained by the amount of good roof or ground space you have available to locate the solar electric and solar thermal panels. In most cases there is not enough room for both of these, so we recommend focusing on solar electric as the first strategy. At present there are many substantial incentives in place for solar electric, making now a GREAT time to look at this solution.

How can I tell if I'm a good candidate for solar?

There are four main criteria:

1. Shade: The most important factor is the availability of un-shaded roof space that faces east, west or south. In order to maximize the benefits of solar energy, you want sun that hits the roof all day long. If you have trees that are shading the roof, ask yourself if you are willing to trim the trees to minimize or eliminate the shading.

2. Age of Roof: Second, you need to make sure that your roof is in good condition, or be prepared to replace the relevant sections of the roof before installing solar energy. Solar systems last a long time, so you don't want to have to remove the system to replace the roof over the short or medium term. Generally, you need to feel that the roof has at least 25 years left on its life. If you are not sure, we can bring in a roofer to evaluate your roof and make a recommendation.

3. Alternate Locations: Finally, if your roof is not appropriate, you can consider a ground-mounted system. To use this option, you need to have enough area on your property that is cleared and receives plenty of direct sunlight.

With solar electric am I still connected to the local utility?

Yes, we provide what are called "grid-tied" systems. This means that you keep your current connection to the utility. Your solar electric system is producing power when the sun is out, so, if you need power in your property, you will be using the solar power. If you need more power than the solar system is producing, you will draw this power from the utility. And, when you are producing more solar power than you need, the power flows out of your property back to the utility and your electric meter turns backwards! You get credit from the utility for each Kilowatt Hour of power you send to them. So, some days you will be a net producer and some days you will be a net consumer of the utility's power. The goal is to size the system so that over the course of a full year, you make as much power as you consume, and thus have no net electricity cost. We will be glad to do this sizing for you!

What happens during a power failure, does the solar system still work?

When the utility power is down, we are required to shut down the solar electric system so that we don't produce power that could hurt the people working on the power lines. So, the answer is no, the solar system does not normally work when there is a utility power outage, unless you supplement your solar electricity system with a back up system.

How can I use the solar system to provide power when the utility is down?

You can add a solar backup system that will work during power outages. This works by adding a set of batteries that are charged by the solar system. Then, when the power goes out the batteries kick in. And, when the sun is out the batteries will get recharged. The cost of the back up system is similar to buying a generator, so you can consider this choice as well for power outages.

How big a solar system do I need?

This depends on your goals and budget. If you want to eliminate your current electric bill, you will need to know how much electricity you consumed in the last year. We will do this analysis for you and let you know what size fits your property, your budget and how much you will save on your electric bill.
