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.

PV can be used to power your entire home’s electrical systems, including lights, cooling systems, and appliances. PV systems today can be blended easily into both traditional and nontraditional homes. The most common practice is to mount modules onto a south-facing roof, or ground mounting.

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.

To avoid system failure, complications or injury, you will want to hire a reputable professional contractor with experience in installing solar systems. PV systems have few moving parts and require little maintenance. The system’s components are designed to meet strict dependability and durability standards that withstand the elements. However, they are fairly sophisticated electric systems to installation which require the knowledge and experience of a licensed contractor.

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. See the video:

Contact us if you have concerns about your system, or you think it’s not generating as it should. We will send someone out to resolve the issue.

The prices of oil and other non-renewable sources are on the increase. This trend will continue, getting more dramatic as shortages of supply increase. The price of your electricity from solar will never increase as the fuel is free and infinite!

Alternating current. An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.

Direct current. Is the unidirectional flow or movement of electric charge carriers (which are usually electrons). The intensity of the current can vary with time, but the general direction of movement stays the same always.

Charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries. It prevents overcharging and can protect against overvoltage.

Florida solar energy center. FSEC is the largest and most active state-supported renewable energy and energy efficiency research, training, testing, and certification institute in the united states.

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.

Is a combination of an inverter, battery charger and transfer switch into one complete system. When ac power is available, the inverter/charger recharges the house batteries. It also allows any surplus ac power to pass through and power downstream ac loads, such as a television set or microwave oven. When ac is disconnected, the unit inverts dc battery power into ac electricity.

A solar inverter changes the electrical current from direct current (dc) to alternating current (ac). See video about “Magic Box

(symbol kwh, kw·h, or kw h) is a unit of energy equal to 1,000 watt-hours, or 3.6 megajoules. The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.

Is a device used in photovoltaics that converts direct current (dc) generated by a single solar module to alternating current (ac). The output from several microinverters is combined and often fed to the electrical grid.

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.

See the video:
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. Net-Zero:

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).

Refers to a photovoltaic module or to a set of solar photovoltaic (pv) modules electrically connected and mounted on a supporting structure.

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

Is a climatological indicator, measuring the duration of sunshine in given period for a given location on earth. It is a general indicator of cloudiness of a location and thus differs from insolation, which measures the total energy delivered by sunlight over a given period.

Understanding Price and Terms

Each PV module has a specific power rating that identifies how much electricity that module will produce at the point the sun is strongest. The ratings from all the modules in a system are totaled to get the full power rating for the system. The cost of your complete system (modules, inverter(s), mounting system, wiring, design, engineering, jurisdictional permitting and installation) is then divided by the total maximum power rating to get the cost per watt.
Example: A 2,000-watt system, that has a total cost of $8,000, is considered to cost $4 per watt.
