We also have an on staff general contractor and professional engineer to help with all design aspect of your project. Our extensive experience and knowledge of the Solar industry’s qualifications and requirements allow us to handle projects of any scope and size. We also carry an unlimited electrical contractor’s license, and have a four Engineers on staff a Mechanical, an Electrical, Civil, and Structural with over 125 years of combined experience dealing with both large industrial and commercial scale projects.

Now I know your biggest question is Why? Why would your company want to add Solar to a project? Well it’s really quite simple . . .The Additional income you will make on normally wasted space by selling the solar energy you produce and don’t use back to the utility companies but more importantly the Huge Energy Tax Credits both through the federal and North Carolina government.

For example currently North Carolina offers a tax credit of 35% of the cost of renewable energy property constructed, purchased, or leased by a taxpayer and placed into service in North Carolina during any taxable year through 2015. Also expenditures eligible for the tax credit include the cost of the equipment, associated design, construction and installation costs to include land acquisition. The federal government also offers tax credits of up to 30% for the purchase and installation of solar systems and solar water heating property for both commercial and residential use.

These are only available when you add solar to your project and many companies recoup most and sometimes all of their initial investment within the first year.

In brief, Green Power of North Carolina has a lot of different products and services we can offer to fit your companies’ future growth plans.

Frequently Asked Questions

What happens when the utility has a power outage?

Most systems we sell are “clean power” systems, without batteries. These systems do not generate power when the utility is out, even if it is sunny. Since we have a robust power grid our outages usually are measured in hours or days and not in weeks. From an economic stand point not using batteries means less start up cost and nothing to replace in 5-8 years. If backup power is desired, a battery system can be added. This increases the complexity and cost. This can also be tied in with a whole house backup generator, to improve over all efficiency and reliability.

How much solar electric power do I need to power my home?

Each home is different, and the amount of electricity you use is very dependent upon your lifestyle, how your home was built, and your appliances. As part of our services, we work with you to reduce your electrical consumption in easy ways.

How long will the system last?

Industry standard on solar panels is 25 yrs. But a 25 year warranty from a tier 3 Chinese manufacturer you have never heard of can still be risky. We recommend a tier 1 company (top 15 largest manufactures in the world) or a name brand you have heard of, Samsung, LG, or Panasonic

How much space does the system need?

A typical system requires about 7 to 8 square feet for each dollar of your electric bill. This figure varies depending upon your electric rates.

Do the solar panels need to be mounted on my roof?

Panels are often mounted on the roof, but can also be mounted on the ground. Ground mounts are great if the house is shaded, or if looking for an out building or other outdoor structure or porch.

Do the panels need to face south?

South is best, but panels installed facing east or west still generate a very high percentage of possible power. It is usually more effective (and more attractive) to install the panels in the same plane as the roof direction, rather than build an awkward mount to angle them.

Are the panels fragile?

No. While the panels are made of tempered glass, it is quite strong. They pass hail tests, and are regularly installed in Arctic and Antarctic conditions.

Do I need batteries with the system?

Batteries are only required if you want backup power when the utility is out of service. Without batteries, the system has no way to store power, and for safety reasons cannot produce power without the utility in operation.

What is Net Metering?

Net Metering is the regulatory ability to get credit for electricity you generate with solar energy and send backwards through your utility meter. Exact provisions vary with each state, but the effect is to allow you to generate excess power during the day, and use it at night, without needing batteries.

What happens if the panels get covered by snow?

Solar electric panels need sunshine to generate power. While some sun does make it through several inches of snow, little electricity is generated when the panels are covered with anything. Most power is made during clear sunny days. Our estimates take that into account.

Do I need to install a new roof before the solar panels are installed?

Solar panels will last many years (over 25). Because of this, we want the roof to be in decent condition, as it does not make sense to remove and reinstall the panels after only a few years. However, after the panels are in place, they will greatly reduce the wear on the roof by blocking ultraviolet rays, keeping most snow and ice off the roof, and keeping anything from hitting the roof. Most installations do not require a new roof prior to PV installation.

What happens if the panels are shaded?

PV panels should be installed in areas where they get significant shade-free sun every day. All of our installs are done with panel level optimization, so even some shading at different place on the array throughout the day is limited as much as possible.

Do I need to clean the panels periodically?

Most of our customers do not clean their panels. In most areas of the country, there is sufficient rain to clean the panels. However, if you are in a dusty area (very near a busy dirt road, very urban area, etc.) you may see a performance gain from cleaning the panels monthly. If necessary, a hose stream is usually sufficient for cleaning. Do not walk on or over the panels to clean them. Do not use metal, hard, or abrasive methods for cleaning. Do not spray water on the panels when they are very hot.

Does solar power work for commercial buildings?

We have worked on office buildings, retail buildings, schools, and government facilities. Anywhere electricity is used, solar electricity can be used.

If I sell my property, what effect does PV have on the sale price?

Energy conservation and renewable generation adds value to a home. Surveys have shown that for every $1,000.00 saved per year, $20,000.00 is added to a home's value. Solar energy can be one of the best home improvement investments you make.

How long does it take to install a PV system?

Typical residential systems take from 2 to 5 days to install. Systems mounted on the ground and systems with batteries are more complex, and may take longer. Most of this time is spent outside your house, so there is little disturbance to you. Commercial systems take several weeks to over a month to install, depending upon size and type of installation. Time from signing your estimate contract to beginning your system could be 2-3 months.
