Almost all roofs can have solar panels installed on them, the biggest factor is the condition of the roof. Other factors such as Material, Pitch, Shape and Size, Orientation, and Amount of shade are also key.

Most states allow "net metering", which is when you produce more power than you consume, creating a surplus of energy that can be turned into credit. Excess power can, in some states, be sold back to utility companies as well.

Numerous studies have shown that purchasing a solar system will increase the value of your property. However, if you have your system installed under a solar lease/PPA agreement, it will most likely not increase your property value.

The primary maintenance includes cleaning and debridement of any buildup that has occurred. This should be done around every 6 months however many factors can come into play. Always read your manufacturer's literature on proper cleaning methods. Occasional repairs, which can range from replacing wires to fixing mounts, can occur. Always make sure to contact a licensed contractor for any of your repair needs.

The majority of solar companies claim that their solar panels will produce at a profitable efficiency for at least 25 years. Over time your solar panels will suffer from a slight degradation of about 0.8-1.2 percent per year of the original efficiency. The degradation is often caused by dirt, pollen, and other external factors, so it is important to remember to clean and maintain your panels.

Nearly every state now offers tax credits as an incentive for citizens to switch to solar power. Depending on where you live, you might be able to use tax credits to subsidize a large part of your solar installation.

Modern solar panel options currently available fit in one of three types: monocrystalline, polycrystalline (also known as multi-crystalline), and thin-film. These solar panels vary in how they’re constructed, appearance, performance level, costs, and the installations each are best suited for. These factors can help you determine which type of panel would best suit your installation needs.

The average home can save between $10,000 and $30,000 over the lifetime of your solar panel system. There are several key factors including the location of the home, cost of utilities, and power consumption.

When you use an electrical appliance, the current flows from your service panel to the device. A grounded wire gives the unused electrical current a safe way back to the service panel so there’s no danger in the event of a short circuit.

This can be broken down into four main steps: Planning and Safety, Wiring and Electrical, Mounting Panels, and Solar Battery Installation.

You may have seen an electrical outlet with a “test” and “reset” button in the middle – this is a GFCI (ground fault circuit interrupter). It automatically shuts off an electrical circuit when it detects that the current isn’t flowing correctly. It’s also used to reduce the risk of electrical shock from a receptacle located in damp locations and/or counter top areas

The National Renewable Energy Laboratory says a 2-kilowatt system, which should offset the electricity use of an average-sized home, estimates the system will cost about $8 to $10 per square foot ($16,000 to $20,000 total) before state and federal rebates and incentives.

Low-voltage fixtures include a transformer to reduce voltage (say from 120 volts to 12 volts). The downside to low-voltage fixtures, however, can be higher installation costs. Also, transformers tend to create heat and mounting locations can be tricky.

LED lights are more expensive to purchase than incandescent lights, but they’re more efficient (they’ll last 50,000 hours instead of 1,200 hours). They also have a lower annual operating cost, which is great for people trying to “go green.”

When the electrical current that passes through a fuse exceeds the limit, it burns a hole in the thin strip of metal. This stops the flow of current and it means you have a blown a fuse. Fuses need to be replaced (not reset). When the electrical current exceeds the limit through a circuit breaker, however, the breaker trip setting opens to stop the flow of current. Breakers are re-settable by flipping the handle on the face of the breaker.

First, make sure there are not too many appliances plugged into one circuit, as this can overload it. If it’s just one appliance, unplug it and either replace it or call us to repair it. You could also try connecting another appliance to the problematic receptacle. If it still shows signs of trouble, have the receptacle and or the circuit checked by our home electrical service experts

The third prong on a plug is a grounding prong. Two-prong receptacles do not have the same level of grounding as a three-prong device. The third grounding prong provides additional protection to the electrical system, the item plugged in, and you from electrical shock.

When you reach to your light switch to turn it off, only to find that it is hot to the touch, you have a problem. This is not a normal phenomenon, and it indicates that there are serious issues hiding behind your walls. If you don't get help right away, you could end up facing a serious electrical fire in your home.

A surge protector is a piece of equipment that suppresses the excess voltage in your system to prevent it from causing harm to your appliances and devices. You should get some to protect your appliances and devices from power surges.

Several years ago, the code was updated and it requires us to install arc fault breakers in the house wherever there are new lines being installed except for where GFCI devices are required (kitchens and bathrooms, etc.). This is a major breakthrough in our industry. This is one of the most intelligent breakers. They monitor the current and discriminate between normal and unwanted arcing conditions. Arc fault breakers are primarily designed to protect against electrical fires caused by arcing.
