If you are living in Perth and thinking of Perth solar installation, you must consider the following factors that will help you decide on the best solar system in Perth. Solar panels or modules have photovoltaic cells made of silicon that convert incoming sunlight into electrical energy. ("Photovoltaic" means electricity from light-photo = light, voltaic = electricity.) Solar photovoltaic cells contain a positive and negative film of silicon located under a thin piece of glass.
As the photons of sunlight fall on these cells, they charge the electrons with silicon. Negatively charged free electrons are attracted to one side of the silicon cell, creating an electric voltage that is collected or passed through the channel.
If you are thinking of setting up solar panels for your home, you need to figure out the following questions.
You should have a fair estimate of how much energy your home uses.
What is your average daily goal?
What is the useful surface area of your roof?
What are the household energy requirements?
In order to do so, take out past electricity bills and look for average usage. Divide the monthly used power unit by 30 to find the daily average. Your answer will be in kilowatt-hours (kWh). (If you run a 60 day bulb 24 hours a day all day, you are using 1,440 watt hours or 1.4kWh)
What is the daily target average?
Solar panels do not always operate at maximum efficiency. Weather conditions, for example, may temporarily reduce the efficiency of your system. Hardware issues also cause the system to generate less energy than expected. Experts advise that you should add 25 percent margin to your household energy requirements to overcome such disabilities and achieve the target daily average.
What is the useful surface area of your roof?
For this, you need to measure the shadow less area of your roof.
A shadow less area means the area that receives a good amount of sunshine in that area from 8 a.m. to 5 p.m.
How many panels will provide my target watts per hour?
Solar panels vary greatly in capability and performance, with panel sizes and modules ranging in weight from 150 watts to 345 watts. Divide your home's hourly energy requirement by the wattage of solar panels, so that you can calculate the total number of panels you need. This will give you the ideal number of panels for your power generation needs. Next, get your roof architecture, sun angle, and other factors assessed by a professional solar installer, who will validate how many panels you need to achieve your daily energy production goals.
Warranties
Solar panels usually come with a 25-year performance warranty. The life of deep-cycle lead acid and solar batteries is 3 to 5 years. Lithium ion and redox flow batteries have a warranty of about 10 to 20 years. You might consider Off Grid Solar installer from a trusted company for better return on investment.
Maintenance
Solar panels generally require very little maintenance as there are no moving parts. Several times a year, panels should be inspected for any dirt or debris that may have accumulated on them. Always make sure that you are safety conscious when inspecting the panels and do not take any unnecessary risks. If your panels are too high on the roof to have a very good view from the ground, be careful with stairs for general cleaning. Just use a standard garden hose to wash the panel face in the morning or evening, avoiding splashing cold water on hot panels. The amount of electricity generated by your solar energy system depends on the intensity of sunlight.
