$200 DIY Build Solar Panels Projects? What you need to know about these projects, who can build a solar panel, what information is required, and what elements make up a solar panel energy system.
Who can build a solar panel?
Anyone can build a solar panel. All you need is some basic DIY skills: use of drills, screwdrivers, hammers, saws and soldering iron. A solar panel is a simple assembly of the solar cells on a backboard with a clear cover, a frame to hold it all together, and some wiring to connect the panel to other panels or your batteries. Anyone can put together a solar panel in just a few hours.
What information you need (Plan – Guide – Materials)
Information is the key! Any project, large or small needs a plan to be successful. Your plan is your overall strategy and includes preparations, scheduling, selecting your guide, gathering materials, building the panels, testing the panels, installing the panels, connecting the panels to your batteries, and then connecting to your home energy supply.
Most important in your overall plan is the selection of your Guide. The guide is your step-by-step procedure on how to assemble, test and install the solar panels.I have reviewed many guides for solar panel projects.
Next we will go over the elements of a solar energy system and discuss the materials you will need.
Overview of Solar Energy System
Let’s take a brief look at the components of home solar energy system. This is a basic system with just the essentials.Obviously, the more elaborate your system becomes, the more sophisticated your setup must be. (More expensive.)
The solar panel is the starting point for your system. Solar cells in the panel convert the solar energy from the sun into Direct Current (DC) electricity. One solar cell typically produces 1/2 volt of electricity. So you will need 36 cells to generate about 18 volts for one panel (18 volts is the minimum required to charge a 12 volt battery). Panels are wired in series and/or parallel to create higher voltages or more capacity (amperes).
A Charge Controller is a device which protects the batteries from being overcharged and prevents the batteries from discharging into the solar panels. This is a very important part of the solar energy system, but is relatively low cost. Typical charge controllers can be purchased for $12 to $25.
The Charge Controller is located between the solar panels and the batteries.
Batteries are required to two reasons. One to provide a means of storing the electricity generated from the solar panels, and Two to provide a regulated buffer from the irregular output of the solar panels. Batteries absorb the highs and lows of the solar cells, such as when the sun is directly producing high output, or when the sun is partially obscured by clouds. To fully meet the above reasons, you should choose high quality batteries such as deep cycle batteries. They are commonly used batteries for solar systems. These batteries regulate solar power flow and provide a constant source of energy for the home energy system
