How to Make Very Cheap Photovoltaic Panels
Photovoltaic panels, also known as solar panels, are a great way to generate renewable energy and reduce electricity costs. However, commercial photovoltaic panels can be quite expensive. In this article, we will discuss how to make very cheap photovoltaic panels using easily accessible materials and simple techniques.
Materials Needed for DIY Photovoltaic Panels
To make your own photovoltaic panels, you will need the following materials:
1. Solar cells: These can be purchased online or salvaged from old solar panels. 2. Glass or plexiglass sheet: To cover the solar cells and protect them from the elements. 3. Plywood or aluminum frame: To mount the solar cells and provide structural support. 4. Silicone sealant: To secure the solar cells and prevent water ingress. 5. Tabbing wire and bus wire: To connect the solar cells together and to the charge controller. 6. Junction box: To house the electrical connections and provide a weatherproof enclosure.
Step 1: Prepare the Solar Cells
Start by arranging the solar cells on the glass or plexiglass sheet in a desired pattern. The most common pattern is a 6×6 grid, but the size and layout can vary based on the available space and the desired electrical output. Once the cells are arranged, solder them together using tabbing wire and bus wire. Be sure to connect the cells in a series-parallel configuration to achieve the desired voltage and current output.
Step 2: Mount the Solar Cells
Next, mount the solar cells on the plywood or aluminum frame using silicone sealant. Be sure to leave enough space between the cells to accommodate the electrical wiring and connections. Once the silicone has dried, cover the cells with the glass or plexiglass sheet and secure it in place with more silicone sealant.
Step 3: Connect the Electrical Components
After the silicon sealant has fully cured, connect the solar cells to the charge controller using the tabbing wire and bus wire. Be sure to use a junction box to protect the electrical connections from the elements. Once everything is connected, test the photovoltaic panel to ensure it is generating the expected voltage and current output.
Benefits of DIY Photovoltaic Panels
Making your own photovoltaic panels can save you a significant amount of money compared to purchasing commercial panels. Additionally, DIY panels can be customized to fit specific space requirements and can provide a sense of accomplishment and self-sufficiency.
Conclusion
In conclusion, it is possible to make very cheap photovoltaic panels using readily available materials and simple techniques. By following the steps outlined in this article, you can create your own renewable energy source and reduce your electricity costs. Whether you are looking to go off-grid or simply want to reduce your carbon footprint, DIY photovoltaic panels are a great option to consider.
