Frequently Asked Questions

Find the answer to commonly asked questions about Solar

As sunlight hits a solar module, photons excite electrons in a silicon cell as they travel from the top layer of the cell to the bottom layer creating voltage and electric current.
This is known as the Photovoltaic Effect.
The electric current travels through a circuit to an inverter and the inverter converts the electricity from Direct Current (DC) to Alternating Current (AC) so that it may be used in your home. AC is the form of electricity that is supplied by your utility.

Solar is a great fit for nearly all situations.

Tax incentives, financing and loan options plus falling material costs have made today a wonderful time to go solar!

In a short time-span solar electric power has gone from relative obscurity to instantly recognizable, reflected in our culture and way of living. Going green and environmental awareness have become some important topics in our lives and our future.

Whether you’re interested in helping the environment, saving on electricity, or both, you can be confident that any questions and concerns you may have can be addressed with SOLARGRAHAM.

Solar electric systems are best suited for areas with little shade and maximum exposure to sunlight throughout the day and year. South, West, and East facing arrays provide for the most effective solar generation and luckily most rooftops are happy to oblige.

  • East arrays capture early morning sun while the array is cool, especially in low desert regions.
  • South facing arrays capture the most sunlight throughout the day and are generally the most efficient.
  • West facing arrays capture sunlight when electricity costs are at their highest, helping curb electric costs later into the evening.

The layout of your home and available space will require from one to all three rooftop directions being utilized.

In some cases, the best option may be a Ground Mounted Solar Electric System with customizable orientation and tilt.  On flat rooftops customizable orientation and tilt will also be employed.

Solar electric systems are sized based upon amount of electricity a household uses from their utility provider and is measured in kWh (Kilowatt Hours). A year’s worth of kWh usage data is collected and the solar electric system is designed to offset as close to 100% of the usage as possible.  In many cases there is simply not enough room on the roof or ground to offset 100% of the usage.  Even in these cases the average price per kWh will be reduced by such a large margin that a solar electric system still makes a great investment.

After installation you will still be connected to the grid. Today’s electric grid is a very stable and reliable source of energy. Being connected to the grid allows you to be part of the NEM (Net Energy Metering) Program.

With NEM, the utility allows you to earn credits while your system is producing more power than you are using, to be used later when your system is not producing at night.

Solar electric systems can also be designed in an off-grid configuration. This requires a battery backup system that will supply power in the absence of the electric grid.  These systems are more expensive and require more maintenance but can be installed in areas with no utility or in places where the utility is not reliable.

For questions about battery back up and off-grid solar electric systems feel free to contact SOLARGRAHAM today.

Grid connected solar electric systems require little maintenance. Changes in season and weather effect the output of a solar system, the longer the sun is out the better. Throughout the year dust will accumulate on solar systems and it is recommended that they be washed off from 1 to 3 times per year. This should be done while it is cool outside either in the morning or at night and can provide up to a 5% increase in production compared to when dirty.

That’s it!

SOLARGRAHAM offers one free complimentary cleaning and cleaning packages that can be added to the purchase of a solar electric system.

In California, the California Solar Rights Act and AB 2188 state that homeowner’s association’s (HOA’S), governments, and other organizations cannot prevent you from installing a solar electric system on your property. Each HOA may have requirements as to general placements and allowable colors of conduit runs if it does not significantly affect the output of the solar system.

SOLARGRAHAM has dealt with hundreds of HOA’s over the years and the process usually has just a few simple steps.

  1. Contact HOA for application
  2. Provide general description of work to be done including contractor info, site plan, and neighbor signatures of understanding that work is to be done.
  3. HOA reviews and approves application and work can commence.
