MC4 and dielectric gease
As I recall, I tucked my MC4 connectors under the panels and attached them to a z bracket to keep the connector in place. Sure, they can still get wet, but some protection is better than no protection. The only problem I see with adding dielectric grease is that it might make the connector prongs a bit slippery, making them come undone easier.

Dielectric grease on cable lugs? Lets test!
Pretty interesting thread. I have thought about this but never found anybody that really tested it. I use dielectric grease all the time in electrical panels. Especially helpful when aluminum meets copper. Also down here in the humid south near the gulf coast it helps prevent corrosion build up on connections.

Can you add solar panels to an existing installation?
For this reason, any panels you plan to add should have the same power rating as the original panels. Again, this issue is avoided by getting micro-inverters, as the solar panels work independently from one another. Roof. Solar panels weigh between 15 and 30kgs, so you''ll need to make sure that your roof can support the added weight and space.

Dielectric Grease
It should be noted that NoAlox is not the same as dielectric grease. NoAlox is actually conductive and improves conductivity because it contains small particles of zinc. Years ago I used dielectric grease on coaxial antenna connections to keep moisture out of the connections. Water would degrade the shield to power isolation.

Solar panel directly connected to immersion heater?
A solar panel is a current source. A 250 watt panel has a Isc of roughly 8 amps. A Resistance Heater is a fixed amount of resistance. A 12 volt 250 watt heater is a resistor with a value of .576 Ohms So you have a current source of 8 amps flowing through a fixed resistance of .576 Ohms. Ohms Law for Power = Current x Current x Resistance.

Solutions for Solar Cell and Module Testing
Figure 2 shows an equivalent circuit of a solar cell along with the series resistance (Rs). By using a slightly negative voltage, you can cancel out the effects of Rs to make a true Isc measurement. The amount of negative voltage needed depends on the value of Rs. For a detailed description on two methods for calculating Rs

How to add dielectric fluid to solar panels
Identifying Compatible Solar Panel Ratings for Parallel Connection. Matching solar panels correctly in a parallel setup is critical. It avoids inefficiencies and ensures all panels add power effectively. When two solar panels of the same wattage are connected in parallel, they double the power output. This is great for expanding your solar system.
