Frequently Asked Questions

Most popular questions about solar system installations and pricing

There are 4 main components of a typical residential solar system:

  1. Solar panels
  2. Inverter
  3. Charge Controller
  4. Batteries

Solar panels are generally installed on a roof or on the ground, facing the sun. They collect sunlight and convert it into direct current (DC) electricity.

The inverter converts DC power coming in from the solar panels and/or batteries into high-voltage alternating current (AC) power to energize your house circuits.  Excess solar electricity can also be sold back to the utility via Net-Metering.

The charge controller regulates solar power flowing into the battery-inverter system.  Charge controllers are only used for off-grid and battery backup systems.

The batteries allow you to store excess solar energy for use at nighttime or during a utility power outage.  We use deep cycle batteries, similar to those found in electric vehicles and boats.

It depends on what your goals are. If you are looking to reduce or eliminate your electric bill, then you probably want a grid-tied solar power system that hooks in with the power company and earns you credit for excess electricity that you generate. If your goal is to run fully independent then an off-the-grid system would be best for you.

  1. A grid-tied solar power system works in parallel with the utility company to save you money. The solar panels will power your home and sell excess electricity back to the utility during the daylight hours. At night, you would continue to purchase power from the utility as normal. This type of system will use all the available solar power to offset your electric bill, earning you the maximum financial return on investment. There would be no need to switch individual circuits. The solar equipment will automatically supply as much electricity as possible. However, there is no emergency capability for a grid-tied solar power system. If the utility service goes down, you will lose power to your home regardless of time-of-day.
  2. An off-grid solar power system works completely independent of the utility company. With this option, you are not going to save much money on a monthly basis. However, you would have the ability to run your appliances even when the utility service is down by using stored energy in your off-grid battery bank. The off-grid type of system is more expensive per unit of energy generated and is best for people who value redundant power for emergency backup over financial return.
  3. Finally, we have hybrid solar power systems, which are able to operate in both grid-tied and off-grid modes, giving you the best of both worlds. When the utility service is up, your hybrid system will power your home and sell excess electricity back to the utility to earn your maximum credit. If the grid ever goes down, the hybrid system can continue to operate using solar/battery power only for an indefinite period of time. Complete hybrid solar power systems start at around $15k, installed.

Yes.  We offer solar financing via our preferred lender, Admirals Bank.  You can finance your solar power system purchase with $0 down over a term of 5-, 10-, or 20-years.  In each case, you own your solar power system from Day 1 and can take advantage of all the tax rebates and incentives.

An off-grid solar power system is a completely stand-alone power generator that includes solar
panels, deep cycle batteries, and various electrical components that allow you to generate clean
renewable power completely independent of the power company. Off-grid solar power systems can be
connected to feed electricity into your house similar to a backup or stand-by generator.

It depends on your electric bill. As a rule of thumb, every 3000W of solar panels you install will offset $60/month from your electric bill. So, for example, if you have an average monthly electric bill of $180/month, you would need a 9,000W solar power system.

We offer complete off-grid emergency backup systems starting at $2995. We also offer complete grid-tied solar power system for a flat-rate pricing of $1.99 per Watt for all equipment and $1.00 per Watt for the professional installation crew. A typical grid-tied system pays for itself in 3-8 years.

So, for example, if you wanted a complete 5,000W grid-tied solar power system, the costs would be as follows:

Solar Kit 5,000W x $1.99/Watt = $9,950

Installation Crew for 5,000W @ $1.00/Watt = $5,000

Grand Total: $14,950

Yes, absolutely! All of our solar power systems qualify for the Federal Renewable Energy Tax Credit, which provides you a 30% refund of your total system cost.

South Carolina residents are eligible for a 25% state tax rebate.

Duke Energy customers in South Carolina are eligible for additional rebates.

Maryland residents are eligible for a $1,000 grant.

P.E.G. will assist you in managing the entire process including: obtaining local building & electrical permits, applying for inter-connection with the electric grid, installing Net-Metering equipment for the local utility, submitting grant applications, setting up your SREC trading account, and providing necessary evidence for the tax rebates.
