Solar Basics: Grasping How Solar Panels Function

To kick off your DIY solar panel adventure, it's key to grasp the basics of solar power and understand how solar panels work. They are made up of photovoltaic (PV) cells that transform sunlight into electricity. These cells are crafted from semiconductor materials like silicon, which generate electric currents when hit by sunlight. The current is then collected by metal contacts on the cell's surface and transferred to an inverter, converting the direct current (DC) into alternating current (AC), ready for use in homes and businesses.

Naturally, this is just a quick rundown of solar power technology, and there's so much more to explore. If you're determined to build solar panels on your own, make sure to dig deeper into solar know how for a more complete understanding.

How to Choose the Right Solar Materials

To create a solar panel that is efficient and long-lasting, knowing how to choose the right materials is essential. Here are some crucial components you will need to make a solar panel:

  • Solar cells: The heart of any solar panel, solar cells can be purchased individually or in bulk. When choosing the cells for your future panel, consider their efficiency, power output, and price. Monocrystalline cells offer the highest efficiency, while polycrystalline cells are a more budget-friendly option. You can also find flexible thin-film solar cells, which can be used to make solar panel for unconventional surfaces.
  • Protective Cover: A sturdy glass or acrylic sheet is crucial for protecting your solar panel from the elements. Tempered glass offers excellent durability and longevity but can be heavier and more expensive. Alternatively, acrylic sheets are lighter and more affordable but may not be as resistant to scratches and discoloration.
  • Backsheet and frame: The backsheet provides additional protection and support for the solar cells, while the frame adds rigidity to the entire panel. Aluminum, with its lightweight and corrosion-resistant properties, is a popular choice for the panel frame. When choosing a backing material, consider factors like weight, durability, and resistance to moisture and corrosion.
  • Encapsulation material: To make solar panel resistant to moisture, dust, and other environmental hazards, you'll need a quality encapsulation material. EVA (ethylene-vinyl acetate) is a popular choice due to its excellent transparency, adhesion, and weather resistance. Be sure to choose an encapsulation material compatible with your solar cells and can withstand long-term exposure to sunlight.
  • Junction box and cables: Lastly, don't forget about the junction box and cables to connect your solar panel to the electrical system of your home. Opt for a weatherproof junction box and UV-resistant cables to ensure the longevity and efficiency of your solar panel setup.

How to Build Solar Panels With Your Own Hands: Step-by-Step Guide

The big moment is here - it's time to take on the most crucial step and build solar panels. Here's the complete breakdown of the process.

Step 1: Solar Cell Preparation

  • Start with inspecting your solar cells for any cracks or damages. If you notice any, replace them before proceeding.
  • Measure the dimensions of your solar cells and calculate the number of cells needed to achieve the desired wattage output for your solar panel. For example, if you're aiming for a 100-watt solar panel, and each cell produces 0.5 watts, you'll need 200 cells.
  • Arrange the cells in an array, ensuring that you have enough space to fit all the cells, plus extra space for wiring and the frame.

Step 2: Solar Panel Frame Construction

  • Measure and cut the frame material based on the dimensions of your solar cell array.
  • Assemble the panel frame with screws, nuts, and bolts, or other suitable fasteners. Make sure the frame is sturdy and can withstand environmental factors such as wind and rain.
  • Attach a transparent cover to the frame to protect the solar cells from dust and debris. This cover can be made of glass or plexiglass, depending on your preference.

Step 3: Solar Wiring and Connections

  • To wire the cells in series, solder the positive lead from one cell to the negative lead of the adjacent cell. Continue with this process until all cells are connected.
  • To wire the cells in parallel, connect all positive leads together and all negative leads together.
  • Now, attach the wires from your solar cells to a solar charge controller. This device regulates the voltage and current supplied to your batteries, ensuring they charge safely and efficiently.
  • Connect the charge controller to your batteries, and then proceed with connecting the batteries to a solar inverter.

Step 4: Solar Panel Encapsulation and Sealing

  • Mix a two-part epoxy or silicone sealant according to the manufacturer's instructions.
  • Apply a thin, even layer of the sealant over the solar cells and make sure that all edges and gaps are covered.
  • Allow the sealant to cure as per the manufacturer's recommended time. This may take anywhere from several hours to a couple of days, depending on the product used.
