How does solar work?
Solar photovoltaics (PV) are devices that convert the sun's light into electricity. When someone invests in a solar system, it will generate electricity on-site and reduce the amount of electricity that must be purchased. A sufficiently sized system can cut an electric bill to nearly zero (there's still a small, monthly fee if you stay connected to the grid).
How many solar panels do I need?
This depends on a many factors such as how much electricity you use, how much of your usage you'd like to offset with a solar system, your budget and the space available. By performing a site-assessment (Free Quote) and working with the customer, we can design a solar system that meets your exact needs.
How does net-metering work?
Net-metering is a policy that lets a solar system owner build credit with a utility provider for any electricity they produce but can't consume by sending excesses to the grid. These credits can then be used to receive electricity when the solar system is producing less than required energy (night time). By using net-metering, a separate backup storage system, like a battery can be avoided, but still an option.
What are the costs of installing a solar system?
The cost of a purchasing a solar system includes but not limited to; the size of the system, how much electricity is used yearly, & the amount of space available for installation. More specifically, the costs include the solar panels, mounting hardware, electrical wiring and processing equipment, along with labor. With the current federal and state tax credits, a solar system can be a very affordable investment, which more than pays for itself with the years of free electricity.
How much space do solar panels take up, & where do they go?
For most commercial customers, we can build on a flat rooftops, or if you prefer a ground mount, the possibilities are endless.
For most agricultural installs, it would be wise to put a ground mount in with all the extra space available. For many residential customers, a solar array of sufficient size can fit on the roof of the residence. If it is determined it cannot fit, a ground-mounted solar system can also be installed.
What if my roof doesn't face south?
South-facing roofs are recommended for solar systems because they receive the most sunlight over the course of a day. East-facing or west-facing roofs can be used as well. North-facing roofs are generally not recommended for solar installations. If a system cannot be optimally designed for a roof, mounting the system on the ground is another viable option.
What sort of maintenance is required?
Maintenance is usually negligible. Solar systems have no moving parts and are very robust. If it hasn't rained for a long while, it is sometimes recommended to clear way any dust or debris with a garden hose, for example. In the winter, snow will usually slide off the sloped solar panels. The sun will usually clear off any snow accumulation in a day or two, if it doesn't slide off.
Will solar work at night?
No, not really. If you're connected to the grid, net-metering (see above) can be used to "store" any excess electricity generated during the day. If you haven't stored enough credits to cover all your electric needs for the night, you can still purchase electricity from the utility just like you could before installing a solar system. If the sun isn't shining, that doesn't mean you won't have electricity. For off-grid applications, some sort of energy storage device, like a battery, is required or perhaps another form of electric generation.
Will solar detract from the beauty of my house?
We sure don't think so. A solar system designed and installed by Green Light will be done so professionally and look great on your home. We also think it makes a statement about you yourself: perhaps you are a forward-thinker, a wise investor or concerned with the future of the Earth.
