Reducing those bills coming through your letter box is something that everybody wants to do. If you can couple this with being green then great. Solar Panels are a top way of doing both. But, should you make your own?
Generating and supplying energy to a wide variety of residential and commercial applications, they are becoming home and business must-haves. And, as with anything, many people have tried their hand at making their own.
With technology improving on an almost daily basis, the big and bulky solar panels of the past have long been improved - leading to price drops and bulk manufacturing. Here is a five simple step list to help you on your way to building your own solar panels:
The Panel - As we all know, the solar panel is where the energy from the sun is collected and channelled.
Charge Controller - The fitting of a charge controller allows the regulation of energy flow. By helping to stop the overcharging of batteries they will have a longer life..
Battery Storage - With the energy being stored in a deep cycle battery, it is advised to keep a battery charged around 80% to ensure longer life.
Power Inverter - The electricity will be stored as a Direct Current (DC), and to get it to be used for household appliances it needs to be converted by a power inverter to Alternating Current (AC).
Start it up - After the purchasing of these four pieces, and they have been built, your household can soon be power by the sun's energy. The thing about solar panels is that regardless of how small (or large) you build one, there will always be scope for adding new panels as and when you want to.
Once the solar panels are set up you soon understand how much money is saved by them. It is generally suggested to have a professional company set it up so you can be guided into creating the perfect system for your needs.
Going green is a commitment, and one that needs to be stuck to. Generally, it will be advised to make photovoltaic solar panels if you are going to have solar energy but with homemade devices you can usually only use passive solar energy. The main issue is that materials are not as simple as they look to manufacture and are very specific, needing to be produced in the right conditions.
Solar panels differ in the amount of volts - the force of the power - and their amps - the flow of charge - that comes from them. Two 10 watt panels may differ by several volts & some amount of amps. This affects how they will charge your battery system.
We're going to keep this simple. There aren't many things worse than math.
When it comes to solar panels, there are watts, amps & volts.
Watts are a measure of the power of a solar panel.
Amps is also referred to as 'current', and is a measure of charging rate.
Volts is also referred to as 'electric potential', and is a measure of the force behind the flow of charge.
Watts is Amps multiplied by Volts (if you remember your high school physics). So a 10 Watt panel is twice as powerful as a 5 Watt panel.
Now to complicate things a bit, you should know that different solar cell chemistry will produce slightly different voltages. For example, a 10 Watt solar panel using the CIGS cell technology (like the panels from Brunton) operate at 16.5V, whereas the PowerFilm amorphous cells create panels that have an open-circuit voltage of 15.6V.
Which is better?
Well, remembering that Watts is Amps multiplied by Volts, it stands to reason that a 10 Watt panel that provides more Amps, will be the solar panel that will charge a battery pack the fastest.
Most solar panels are designed for use in what is termed "12 Volt systems", even though "12V" is not actually an accurate term. 12 Volts is used because this is the nominal voltage of a car battery, and is an easy multiple of 120V AC power that you find in your home. A lead-acid battery like the one in your car, contains 6 cells operating at 2 Volts each. A 12V battery is actually just over 13V when it is completely full, and somewhere around 10.5V when effectively empty.
Lithium batteries have followed this convention as they were the latecomer to the scene.
Charging batteries is somewhat like siphoning water from one bucket to another. As long as the charger has a higher voltage than the battery it is charging, charge will flow between them, and the battery will get charged. This is why solar panels are designed to be 15-18V, in order to properly charge a 12V battery. Charge controllers are used to make sure that the panels do not overcharge the batteries once they are full (in the siphoning example, this would be like closing a valve on the hose once the second bucket is full).
Since lithium batteries are everywhere in small electronics, the personal solar chargers are designed around them. This is why the USB format has become the standard for charging small electronics - the 3.7V lithium cell charges from the 5V USB. Lithium batteries in small electronics also comes with their own built-in controller that stops them from being charged once they are full.
