How do solar panels generate electricity?
Solar panels absorb energy from the sun by way of a semiconductor (typically silicon) and generate direct current electricity. An inverter can then be used to convert direct current (DC) electricity to an alternating current (AC) electricity to match any electrical loads that operate on AC electricity.
Can I install solar PV (photovoltaic) panels at my home or business?
Yes, as long as the selected location is clear of obstructions that will block sun light. Although shading may be unavoidable, the location should remain unshaded for the majority of the day or peak sun hours.
How can I use solar panels to power my house at night?
Although solar systems do not generate power at night, battery storage may be ideal to provide power when the solar system is not performing. Although battery systems can provide plentiful and reliable power when properly designed, battery systems are typically costly and require additional monitoring & maintenance. Most customers remain connected to the utility grid for continuous access at all times.
What size PV system is needed to power my home or business?
System sizing depends on your average power consumption and the percentage of power you intend to offset from your utility. By observing your monthly and annual usage found on your utility bill, an ideal PV system size can be calculated. Once the ideal system size is calculated, suitable areas for a roof or ground mount system free of shade and obstructions will determine options available for you.
How much does a typical PV system cost to install?
The installed cost of Solar PV systems can range from $4,000-$7,000 per kW depending on the technology, system size, and location. We would be glad to provide a system to meet your budget.
How long does a typical solar panel last?
Most solar panels are under warranty to produce 80% efficiency for 20-25 years, although many panels are known to perform in excess of 40 years.
Is maintenance required for PV systems?
Minimal maintenance is required. Panels should be cleaned of debris, and anything that can block the sun to ensure maximum output. Some components may need regular inspection by a professional.
Will my PV system work during a power outage?
Most Grid-connected PV system will not produce power during a power outage due to two reasons. The electronics that make up the system has to adjust voltage and current in order to keep the system running properly. Without grid power the inverter will not work. Also during a power outage federal regulations state that a grid tied solar system must have a rapid shutdown to prevent any back feeding of power into the utility lines. This protects the utility lineman working on the service lines from electrical shock. A battery backup system is available that will allow you to keep power on during a power outage.
