Introduction to DIY Solar Panel Frames

When building your own solar panel is a great advantage that there is no shortage of materials or type of materials.

But there are some important factors to keep in mind when choosing your materials such as:

  • Material durability
  • Construction methods
  • The availability of the materials
  • Finance costs

Your solar panel framework needs to environmental threats, such as precipitation, wind, temperature, etc. Intrusion resist

The frames must be rough to protect the valuable and fragile solar cells, during the installation phase.

For some areas of the frame should heavy wind pressure, hail or snow to withstand loads.

There are cases where PV panels are used only occasionally for small batteries, and therefore not to deal with harsh environment on a daily basis.

These types of PV panels can get away with more inexpensive materials.

Without doubt the most important factors affecting solar panel lists are heat- and moisture resistance.

Thermal Resistance For Solar Panel Frames

All the solar panels are exposed to extreme temperatures, from freezing winters very hot summer days. These seasonal variations in the temperature may result in a distorted panel frame if the appropriate materials are not used.

Extreme temperatures cause bend the material of the solar module frame and contract at different rates, depending on the materials.

, since the material otherwise in a pv frame, they will shrink and eventually deform different speeds from one another. Because of this special attention

In winter, when temperatures are very low, binders tend to crack and separate them from other materials that different shrinkage rates. [19459005wordengegevenaandebindmiddelenenhunlevensduur]

In the summer, the opposite is true and soften and decompose binders that leads to the breakdown of the panel and lower performance.

Moisture Resistance for solar panel frames

Almost all solar panels with moisture in one way or another. Factors such as melting snow, rain, or fog must be taken into consideration before the construction of the frame.

Many materials have a tendency to absorb moisture and warp, over time, attract moisture to the inside of the panel in which the solar cells and electrical connections are made, eventually leading to panel failures.

For moisture you need to use binders with a high moisture resistance and fasteners that can withstand prevent corrosion.

The panel must have to a certain degree of flexibility of the mechanical parts. They have to contract and expand in tandem, so that the correct mechanical connections are important.

Personally we use Silicone 2 for bonding purposes, such as a high degree of flexibility for expansion and contraction. Silicone 2 is also a good seal against moisture.

UV resistance for solar panel frames

Another factor affecting solar frames UV degradation. Some materials have a tendency to break when faced with constant exposure to UV and eventually lead to moisture and extreme temperatures, degrading the panel.

For UV vulnerability we used silicon to aluminum and plexiglass in our frames against. Tough not the best, these materials give the best bang for the buck when cost and availability are taken into account.

plexiglass can also be replaced with polycarbonate or glass fiber.
