Monocrystalline Solar Panels are lighter but powerful than other types. Their rigid, black frame design allows them to blend seamlessly with the roof of homes or businesses.

Renowned companies like SunPower started manufacturing Monocrystalline Solar panels in the year 1985, revolutionizing renewable energy generation technology.

Monocrystalline Silicon Technology has been around since the late 1950s in the United States military space program and it was utilized in NASA’s space race efforts in the ’60s.

Polycrystalline solar panels are like a bag of mixed candies, you never know what you’re gonna get in terms of efficiency and power output.

Polycrystalline Solar Panels

Polycrystalline solar cells are a type of photovoltaic technology that converts sunlight into electricity. Looking at their structure, multiple silicon fragments make the panel. In comparison to monocrystalline panels, polycrystalline solar panels are cheaper, less effective in terms of energy conversion rates but they work better in low light and hot conditions.

The following table depicts a comparison between Polycrystalline and Monocrystalline solar panels:





Speckled blue color and rectangular shape.

Oblong shape with smooth black color.

Pricing/Per sq foot (as per industry standard)

$0.33 – $0.43

$0.34 – $0.47

Average output per wattage rating as per CEC maximum standards

16% efficiency with an output range of 270W-325W+/-5%

17% efficiency with an output range of up to +/-15% depending on the manufacturer’s specifications.

Another point worth mentioning is that polycrystalline technology can be used in larger installations where higher cost efficiency is needed, such as utility-scale projects or even small residential-scale applications.

I’ve met a retired couple last year who shifted to using polycrystalline solar systems in their housing complex for energy and power generation. They were quite happy with their roofing system after installation, explaining that aside from the lower upfront and installation costs of polycrystalline, it also needs minimal maintenance. Don’t let their thin appearance fool you, these solar panels still have enough juice to power a California-sized ego.

Thin-Film Solar Panels

Utilizing cutting-edge technology, Photovoltaic film panels are a modern variation of solar panels and are commonly known as Thin-Film Solar Panels. These panels are lighter and have a higher level of flexibility than traditional silicon-based solar cells.

Thin-Film Solar Panels




Cadmium Telluride (CdTe)

The most widely used thin-film system, cost-effective and efficient even in low light conditions.

Low manufacturing costs, able to absorb sunlight at different angles, lower carbon footprint.

Environmental concerns due to the toxicity of cadmium, less durable and shorter lifespan than silicon panels.

Copper Indium Gallium Selenide (CIGS)

An emerging alternative to CdTe technology.

Inherently flexible, more efficient with higher conversion efficiency rates compared to other thin-film technologies.

Safe disposal can be a challenge due to potentially hazardous elements.

Pro Tip: To ensure maximum efficiency from Thin-Film Solar Panels, optimal installation is key. Location and direction must be taken into account for optimum performance.

Going solar in California might cost you an arm and a leg, but trust me, it’s worth it to save the planet and impress your neighbors.

Installation Cost

The cost of setting up solar panels in California includes installation fees. These expenses depend on various factors, such as the complexity of the installation, system size, labor costs, and permitting fees. A larger system that requires more work may cost more to install than a smaller one. Labor costs also vary with location, with urban areas tending to be pricier than rural ones.

Additionally, permit processing fees and other paperwork must be taken into account when calculating the final cost. The required permits can vary depending on where you live and what kind of solar energy system you are purchasing. These permits can add up quickly and are highly regulated in California.

Notably, it is important to use high-quality materials while installing solar panels; using substandard materials may lower the initial costs but will increase maintenance expenses later on. Therefore, selecting good quality products from reputable suppliers is important for a long-term investment in your home’s energy efficiency.

According to a recent study conducted by Berkeley Lab, the average installation cost per watt of solar energy in California was $3.70 in 2020 (source). This study suggests that homeowners should expect to pay around $18,500 for a 5-kilowatt solar panel system before any tax incentives or rebates.
