Frequently asked questions:
Yes! Solar is a great and secure investment, better than investing your money in savings accounts or IRA’s.
If you are looking for an ethical place to put your money then solar PV will benefit you and the planet.
A PV system that is designed, installed, and maintained well will operate for more than 30 years at 80% of performance. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years.
The best way to ensure and extend the life and effectiveness of your PV system is by having it installed properly. Experience has shown that most problems occur because of poor or sloppy system installation.
The installed cost of a PV system will depend upon the size of the system (based on your consumption), the roof type, the type of modules and mounting style. Solar systems are half the cost from years ago and there are federal tax credits available to help you reduce the cost of the system.

The average domestic system will take 5-8 hours to install.
When certain semiconducting materials, such as certain kinds of silicon, are exposed to sunlight, they release small amounts of electricity. This process is known as the photoelectric effect. The photoelectric effect refers to the emission, or rejection, of electrons in response to light.
Solar PV generates electricity from light (photons). The more light that shines on them the more energy they produce.
NABCEP is the most recognized and esteemed certification the solar industry offers. A NABCEP certified contract is to the solar industry as a Master Electrician is to electrical contracting. Certification offers the public a high degree of protection because practitioners must voluntarily meet standards and qualifications and pass exams. NABCEP Certification is the ultimate validation of experience and knowledge in the growing solar industry.

Also called tied to grid or grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is generated, or the batteries are not fully charged, electricity drawn from the mains grid can make up the shortfall.
A solar inverter changes the electrical current from direct current (dc) to alternating current (ac).

A packaged, connected assembly of solar cells.
Or maximum power point tracker is an electronic dc to dc converter that optimizes the match between the solar array (pv panels), and the battery bank or utility grid. To put it simply, they convert a higher voltage dc output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.
The North American Board of Certified Energy Practitioners (NABCEP) offers entry level knowledge assessment, professional certification, and company accreditation programs to renewable energy professionals throughout north america.

Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. For example, if a residential customer has a pv system at the residence, it may generate more electricity than the home uses during daylight hours. If the home is net-metered, the electricity meter will run backwards to provide a credit against what electricity is consumed at night or other periods where the home’s electricity use exceeds the system’s output.
National Renewable Energy Laboratory. Is the united states’ primary laboratory for renewable energy and energy efficiency research and development. The national renewable energy laboratory (nrel) is a government-owned, contractor-operated facility, and is funded through the united states Department of Energy (DOE).
Also known as a remote area power supply (RAPS), is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system.
An example would be our Youtube Studio on Solar Energy. It is completely Off-Grid
Understanding price and terms
Example: A 2,000-watt system, that has a total cost of $8,000, is considered to cost $4 per watt.
