A solar power system is made up of 4 major components: solar panels, inverter, battery, and power meter. Solar generated electricity is created by using technology field-tested and improved upon since the 19th century. When sunlight hits the module on a solar photovoltaic or PV installation, solar panels convert the sun’s energy into electricity that can be used to power your home.
- SOLAR PANELS: https://mysunbank.com.au/solar-panels-made/
Solar panels are made of tempered glass and a non-reflective outside layer meant to provide environmental protection. The top of the solar panel has a conductive electrode that typically acts as the cathode (negative electrode). This is followed by a nice thick layer of either n-type or p-type semiconductors.
N-type solar panels: Have more free electrons than atoms
P-type solar panels: Have less free electrons
The top layer is followed by the depletion zone and then the opposite type material is on the other side of this zone.
The bottom layer of the solar panel is the opposite electrode – anode (positive electrode). Sunlight has photons in it that are energized, this energy is imparted to these photons from the chemical reactions that are happening in the sun!
This energy from the photons is then transferred to the semiconductor materials in the solar cells creating a steady flow of electrons. This flow of electrons is then harnessed by the inverter creating AC electricity that can be used to power your home or business!
The solar inverter is a device that converts DC power generated by the solar panels into AC power that is used by homes and businesses. A series of panels will be wired to the inverter to convert the incoming solar energy into usable energy. The inverter will usually be in a safe place and easily accessible for maintenance. This may include locations such as on the side of your house, in a garage, or in your basement.
A solar battery is an energy storage device installed to take the extra power produced by most solar PV systems during the day and store it for use either at night OR in an outage situation. Most residential battery solutions available right now have a storage capacity of around 9.8 kWh or more. Depending on the critical loads connected, these can last anywhere from a day to a couple of days if it is sunny outside and recharging can happen. Multiple batteries can also be added to increase the desired battery life and provide longer backup times.
- POWER METER:
For systems that maintain a tie to the utility grid, the power meter measures the amount of power used from the grid. In systems designed to sell power the utility, the power meter also measures the amount of power the solar system sends to the grid.
How Long Do Solar Panels Last?
The design and technology of solar panels has been improved upon for years to bring you a long lasting energy generator. Solar panels have a high guaranteed output for the first 25 years of their life. In fact, some solar panels last 40 years after installation with an operating output of around 80%.
With the Green Day Power Forever Solar program, if you purchase your system from us and anything breaks, and it can be fixed, we will fix it free forever. You will be forever confident with the best warranties in the industry and you will be working with forever experts.
Is your home right for solar?
Does your roof have unique angles? Are some trees casting shade and you are wondering if that is bad? We train our installers in every facet of roofing and solar installation and we never use subcontractors. Everyone working on your home is an employee of Green Day Power. Experts only on your roof! Make sure any solar company you choose has a roofing license. Just walking on your roof can cause damage, so you need an expert.
Are Solar Panels Worth it?
The benefit of solar panels is straightforward – when you install solar power for your home, you generate your own electricity, become less reliant on your electric utility and reduce your monthly electric bill. Solar panels help you save money and utilize an efficient renewable energy resource. Even during the winter months or rainy days, solar panels will continue to produce energy because AC power is created from light, not heat.
The average Green Day Power customer saves thousands of dollars by going solar in 2020. The overall amount you save in investing in solar power is where the value lies.
