WHAT SOLAR ELECTRIC SYSTEM DESIGN TYPES ARE AVAILABLE?
Solar energy systems are either Grid-Tied or Off-Grid.
Grid-Tied Systems are the most common type of solar electric system. With net metering, which is available in New York, the utility company stores the power from your solar array when you produce excess electricity—and delivers it back when you need it, at no cost!
Off-Grid Systems are a good solution if you want complete independence from utility companies, or if you need for remote locations where electricity is not available. Batteries are used to store the electricity generated by the arrays for use at night.
Net metering allows customers who generate their own electricity from alternative energy systems, such as solar, to transfer electricity they don’t use back into the grid in exchange for credits on their utility bills.
Here’s how it works:
- During the day, a solar photovoltaic (PV) system produces electricity for immediate or “real-time” use
- Any extra energy not being consumed at the site is sent to the utility grid
- When your PV system doesn’t supply your entire daytime needs, and/or at night when your system isn’t producing, energy is supplemented from the utility.
- At the end of a billing cycle, any credits earned during extra production times are used to offset electricity usage at other times.
- If you have credits remaining at the end of the year, the utility will send you a refund check calculated based on the number of credits and the “avoided cost of power” dollar rate.
- Most cost-effective solution
- Home/garage/barn acts as system support
- Mounting structures connected to the ground with several pillars
- Typically installed in rows and positioned to collect maximum energy
- Offer maximum options & flexibility for set-up and location
- Optional tilt-racks and tracking systems for more efficient energy collection
