We will briefly consider each of these factors below to choose the best residential solar in San Luis Obispo County you need but smart72 can always help you to make the right solar choice .

The Type of Solar Panel

The three major types of solar panels are monocrystalline, polycrystalline, and thin solar panel. Monocrystalline silicon panels are highly rated and boast of higher efficiency ratings, requiring less space to produce the same amount of power compared to other types. It is the most expensive but its electricity production will still decrease when the panels are subject to shade, dirt or snow.

Polycrystalline silicon panels are cheaper than monocrystalline panels but also a little less efficient. But their efficiency is also commendable. They also require more space.

Thin film panels are the cheapest among the trio. Their performance are not often great but they are highly flexible and can be used in different ways. They are also not durable.

Ratings of Solar Panels

When shopping for solar panels, you will notice that they are rated based on cost per watt ($/watt). Do not let this confuse you as higher value does not necessarily mean higher efficiency. It may be an indication that the panel is simply bigger. You need to consider this power output with efficiency rating but buy the panel that can deliver high power and can be accommodated by your roof.

Cost Vs. Value

Many individuals assume that a higher cost means higher quality but this may not be the case on several occasions. You need to understand the specifications that really matters so that you can buy a solar panel that the cost will be a true reflection of the value it can deliver to your household. The specs will reveal how heavy the panel is, how much space it will require, as well as how temperature impacts it. Consider watt and size, dimension, weight, durability, back sheet, tolerance, temperature coefficient, conversion efficiency, glazing, and embodied energy. smart72 can always help you figure out the right panel for the right value in San Luis Obispo County.
