-Dara O’Farrell

“Best contractor experience of any kind that I”ve encountered in San Francisco. Great, talented, efficient people.

-James Lynch, San Francisco

“Sun Light & Power designed and installed the PV system currently in operation at my home in Orinda. I am very satisfied with the service and work they provided. They were very pleasant and professional from beginning to end, and I have enthusiastically recommended them to serveral friends who were considering PV systems.

-John McGonigle, Ornida

About Solar Electric Power

Solar electric modules convert sunlight into electricity through a system that uses almost no moving parts and produces no air pollution.

Sun Light & Power has designed and installed hundreds of solar energy systems, addressing the energy needs of homeowners, businesses, contractors and architects. By taking advantage of both “tiered” and “time-of-use” utility rate schedules, a well-designed solar electric system has the potential scale back your electricity costs to zero while generating only 70 to 80 percent of the electricity you actually use. Here’s how:

Tiered Rate Plans

Most utilities bill their customers on “tiered” rate plans. Every month begins with a baseline allocation of relatively low-cost power. As you consume more electricity during the month, the rates increase. A kilowatt-hour (kWh) consumed at the end of a given month can cost more than three times as much as the first kWh consumed that month. When you install a solar electric system and reduce your consumption of grid power, the cost savings accrue beginning with the most expensive price tier – so a relatively small solar electric system can generate disproportionately large savings on your electric bill.

Time-of-Use Rate Plans

Many utilities also offer “time-of-use” (TOU) rate plans, with higher rates charged for electricity consumed during periods of peak demand. TOU pricing is particularly beneficial for homes with solar electric systems, because the highest electric rates typically apply on summer afternoons when solar panels generate the most electricity. If your system generates more power then you consume during peak hours, the excess power will flow back to the grid and the utility effectively buys the electricity from you at the peak period rate. During night and evening hours, electricity that you buy from the grid will be priced at the lower off-peak rate.


Solar Modules

Solar electric modules – also known as photovoltaics, or PV – are made from special silicon cells that produce direct current (DC) electric power when exposed to sunlight. They can be installed on the roof, ground, carport or any other adjacent structure.

Power Inverter

The DC power created by PV modules flows to an inverter that converts DC current into alternating current (AC) to power your home’s electrical outlets, lighting, HVAC equipment, etc .

Electric Meter & Service Panel

The AC power flows from the inverter to the main electrical service panel for distribution to the building’s electrical system. Your existing electric utility service remains in effect, and your power meter continues to measure consumption, allowing you to draw power from the grid whenever your PV modules are producing less power than you need.

Selling Back to the Grid

Any time the solar electric modules are producing more electricity than your home is currently using, the excess power automatically flows from your home back into the public utility grid. Your electric meter is able to measure how much excess power your system generates, and under the terms of an “interconnection agreement” (also known as “net metering”) between you and your power company, the utility is obliged to credit your account for the excess power your system generates, up to the amount that you actually use in a given year.
