The main factor would be your usage. Most of our clientele want to produce enough energy to completely eliminate their electricity bill, but there are several other factors that determine the ideal number of panels. Some of these factors are the direction of your rooftops, the shading present, and the size of panels that will be installed on your property. A south facing rooftop will produce the most energy, followed by west and east facing rooftops. North facing rooftops are not ideal, but there are some solutions to maximize the production of those rooftops as well. Your plans for the future should also be considered. Some questions to consider: Will your family be growing? Will you be purchasing an electric car? The first step to accurately answer this question is speaking with a solar consultant who is trained to consider all of the variables and present the ideal system size for your home or business.
A well designed and competitively priced solar power system should lower your monthly electricity costs significantly. Your savings will depend on your usage, how much electricity your solar panels generate, and how much your utility charges for electricity.
The first benefit a new solar customer should experience is a lower electricity, but solar is also a great way to hedge against rising energy costs in the future. The Federal Solar Tax Credit provides the option of a 26% reduction on the cost of solar, so that percentage of your tax dollars are invested back into your home as long as you meet the requirements to receive the credit. Some utility companies are still offering incentives to go solar. Your consultant is trained to outline these and other benefits that may be available to you. Many studies show that a homes value will increase with the addition of a solar power system as well. Of course, each circumstance is unique and should be considered at the time of purchase.
There are several benefits which compound as more and more of us chose solar, but the most important is a move toward sustainability and the reduction of greenhouse gas emissions, Greenhouse gases, which are produced when fossil fuels are burned, lead to rising global temperatures and climate change. Solar energy decreases greenhouse gas emissions, particularly carbon dioxide (CO2).
Simple explanation: Solar panels absorb the suns electricity and convert it into direct current (DC). This direct current is directed to an inverter which converts the direct current (DC) to alternating current (AC). That alternating current (AC) is fed into your electrical panel and available for your home to use. In most cases, any extra electricity is absorbed into the utility grid and returned as an energy credit for later use in your home. Extended Technical Explanation: Solar panels are comprised of photovoltaic cells. These cells are made of a semi-conducting material, usually silicon. Many cells linked together make up a solar panel. To work, photovoltaic cells need to establish an electric field. Much like a magnetic field, which occurs due to opposite poles, an electric field occurs when opposite charges are separated. To get this field, manufacturers “dope” silicon with other materials, giving each slice of the sandwich a positive or negative electrical charge. The solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow. Metal conductive plates on the sides of the cell collect the electrons and transfer them to wires. At that point, the direct current of electrons flows to an inverter, converting it to alternating current that is directed to the electrical panel to be used by the home or business.
There are several mounting systems used to install solar panels on a rooftop. The type of mounting system will used depends on the type of roof (shingle, tile, flat, etc) and brand preference of the installer. Typically, penetrations are made for footings which support the racking that the panels sit on. The areas where the roof is penetrated are weatherproofed to prevent leaking and wiring is run in conduit to the inverter and electrical panel. In some cases micro-inverters are installed below the panels and then run directly to the electrical panel. In some cases, especially those with very large sized residential or commercial projects, ground mounted systems are installed, in which case the panels are installed on a racking system with concrete footings installed directly in the earth. Most solar installations take 1-4 days depending on the size and complexity of the installation. Solar X uses premium installation equipment to insure the highest quality installation on your home or business.
Solar X has greatly streamlined our internal processes allowing us to install most of our systems within one month of the final design approval by our customers. In circumstances where an HOA, permitting, financing, or construction delay occurs, we are still often able to install within 45-90 days. This is much faster than the typical 3-6 months to install quoted by most solar companies. We offer a 90 day installation guarantee to assure that our customers receive the most efficient project timeline possible, but there are some cases where the install timing is beyond our control.
