Matched Cells
The weakest cells in a system will be the limiting factor - much like the weakest link in a chain determines its strength. Most don''t bother to buy matched cells due to the significant premium associated with LEGIT matched cells. You haven''t stated 12, 24 or 48V, but since you are willing to buy 4 at a time, that suggests 12V.

6 FAQs about [How big a switch should a 32w solar cell be matched with ]
How much power does a 200 watt solar panel produce?
If the 200 watt panel is a GT panel and the others are not, you have a mismatch which is hurting your efficiency. Two small panels in parallel should produce a max of 17.4v and 11.5a. Those are then wired in series to the large panel which should result in 35.6v (mis quoted above at 39v) and 11.27a. I'm definitely not getting that.
How to determine the dimensions of a solar panel?
To determine the dimensions of a solar panel, first, you need to estimate how much watts of electricity you may require for the specified load. In order to exactly determine the dimensions of the solar panel, batteries, charge controller and inverter, the following parameters will need to be strictly calculated and configured.
What is the wattage of a solar panel?
To calculate the true power for a solar panel that would enable a load to keep running throughout the year, we consider the 4 to 5 hours of sunshine per day. Therefore, 200 Watt solar panel is required based on 1,000 Watt hours and 5 hours of sunlight.
How many watts / 5 hours sunlight / 200 watt solar panel?
200 Watt solar panel provides 1,000 Watt hours of electricity under 5 hours of sunlight.
How much power does a solar panel need to provide?
To calculate the power required from a solar panel, multiply the power of the load by the hours of operation. For example, a 100 watt load that needs to be operated for 10 hours would require a total power of 1,000 Watt hours.
What voltage is a switch rated for?
For a similar current rating, the DC voltage rating on a switch will generally be much lower than its AC equivalent. For instance, a switch rated for 15A at 250 Vac will only be rated for 15A at 12 Vdc. Selecting a Certified Switch
