Efficiency: This rating measures the percentage of energy a solar PV module captures from the photons falling on it’s area. Commercially available PV modules usually capture between 10 to 20. Our ratings are as follows:
<11% = *
11-12% = **
13-14% = ***
15-16% = ****
>16% = *****

Long term degredation: This rating measures the how much performance a solar PV module loses as it degrades over time. Our ratings are as follows:
>24% = *
20-24% = **
15-19% = ***
10-14% = ****
<10% = *****

Warranty: The length of warranty offered on this PV module. Our ratings are as follows:
<6 years = *
6-11 years = **
12-17 years = ***
18-23 years = ****
>23 years = *****

Manufacturer stability: The likelyhood of the manufacturer being in business long enough to honor their entire warranty. We carefully research all our product manufacturers considering: past history, current financial outlook, business model, and future goals to develop our rating. Our ratings are as follows:
Bankrupt or out of business = *
Insolvant and losing money = **
Weak but solvant = ***
Stable = ****
Strong = *****

Build quality: This rates the quality of the manufacturer’s product. When we develop this rating, we consider the following factors: level of integration, country of production, our observations of the product, production process, and corporate reputation. Our ratings are as follows:
Unacceptable = *
Poor = **
Average = ***
Good = ****
Excellent = *****

Kyocera PV modules are manufactured to last, with a rated drop in production of only 5% over 25 years. Kyocera PV modules also have an industry leading -0/+5 percent tolerance. In any central inverter system, your PV modules (wired in series) are limited to producing only as much as your weakest PV module. Since Kyocera PV module efficiency only varies by 5%, you’ll loss less efficiency from PV module variance than similar systems with other PV modules.

Every Kyocera PV module comes with a 25 year warranty, only available to Clary Solar Kits customers. Kyocera is financially strong. They have been in business since 1959 and their debt to income ratio is lower than most manufacturers in the industry. We expect them to be in business for the life of their warranty.

Sharp PV modules are a high quality standard in the solar industry. They have excellent efficiency for the price, good duribility and come with a 25 year warranty.

Sanyo HIT panels are designed to compensate for high temperatures reached by solar panels during production periods. Sanyo HIT’s produce 10% more than similar panels at a given temperature. Sanyo HIT panels are also significantly more efficient than other panels, with a 17.2% sunlight conversion rate. This allows more power to be generated in a smaller amount of space.

Sanyo panels come with a 20 year warranty. Sanyo is currently in a strong financial position and we expect them to be in business for the life of their warranty.

Efficiency: The rating measures what percentage of DC power is lost in the conversion to AC power. Our ratings are as follows:
< 90% = *
90-95% = ***
> 95% = *****

Expected lifespan: This measures the inverter’s lifespan. Our ratings are as follows:
< 10 years = *
10-20 years = ***
> 20 years = *****

Warranty: The length of warranty offered on the inverter. Our ratings are as follows:
< 10 years = *

Enphase M190 microinverters are the central piece in the unique and innovative Enphase microinverter system. Unlike the more traditional central inverter system, the Enphase microinverter system has one inverter per panel.

Because the Enphase system is wired in parallel, the failure of one panel will not affect any other panels in the system. This configuration also allows every panel to produce it’s maximum power rating, instead of being limited by the weakest panel in the string, increasing efficiency. The Enphase system also comes with real-time monitoring of individual panels, not available in any other system.

Every Enphase microinverter comes with a 15 year warranty backed both by Enphase and Clary Solar, Kits. Enphase is a newer company, but is in a stable financial position. We expect them to be in business for the life of the warranty.
