Generating Power and Saving Money With Photovoltaic (PV) Panels
Photovoltaic panels or PV solar panels are an array of silicon crystals impregnated with conductive elements like boron and phosphorus that create Direct Current electricity via the radiation present in sunlight. When sunlight strikes the surface of PV solar panels, electrons activated by the phosphorus and boron in the panel move across the solar panels and generate electricity, which is then converted to Alternating Current using PV Inverter. Photovoltaic energy is a clean, renewable resource currently in use in over 100 countries worldwide, and has numerous home and commercial applications, dramatically offsetting utility costs and resource depletion in an increasingly electricity-heavy world.

How do Photovoltaic (PV) Panels work?
A PV panel is a semiconductive substrate such as silicon or cadmium that has been impregnated with conductive elements such as boron and phosphorus. Silicon is the best substrate, due to natural conductivity, and the larger the crystal of silicon used, the better the conductivity. Copper cables connect each unit in the array, as well as the PV Inverter. When sunlight hits a Photovoltaic (pv) panel, the electrons in the silicon, activated by the boron and phosphorus, move across the panel and through the copper cables, creating electricity. When this happens, Direct Current is created, which is then harvested and converted into a usable form for the consumer via PV Inverter. Energy is then stored for use, or exported to the local utility grid using net metering. PV panels have been in use for over fifty years, with grid connected solar panels in common usage for the last twenty. There are no moving parts needed for full conversion of sunlight into useful energy, and no environmental emissions are produced during the process.
What is a PV inverter?
A solar PV inverter is the component of any solar array that converts the electricity generated by your PV solar panels into electricity usable in your home. This may be a standalone unit, a grid-tie unit, or a battery backup unit. Each of these types of inverters is specific to the type of array with which it is used, and each offers its own set of advantages and limitations. Standalone units are required where the solar panels do not interface in any way with the utility grid, storing solar power in batteries to be drawn from and converted by the Inverter. Grid tie units interface with the local utility grid, and may make use of net metering. They are designed to shut down automatically in the event of grid failure for safety, and therefore do not provide energy backup during utility blackouts. Battery backup units are designed to draw energy from a battery, providing backup during utility failure, and export excess electricity to the local utility grid.
How can Solar Panels save money?
By offering an alternative source for the energy you consume in your day to day life, the cost of installing a solar power array for your home or business can be recouped in as little as a year and a half in some regions. Most solar panels generate more energy in a day than you use during that period, in which case the excess is either stored, or fed to the grid for use by other local loads. Many solar panel services recommend installing a battery bank for storage of raw energy. Solar energy accumulated during sunny periods can help offset the energy used from the local utility grid during overcast periods, and excess energy can be stored for later use using battery banks, or in some areas fed back to the utility company in exchange for credit via net metering. In this way, not only are you spending no money on electricity when the sun is out, your excess electricity is siphoned back to the utility company, literally causing your electric meter to run backwards, saving you even more money on your next power bill.
