He's a pretty good source, especially in regards to proper (higher) charging
voltage for batteries
, most battery
banks are only charged to 80%, giving only 30% of cap instead of 50%.
My only caution about his solar
system design philosophy is he did it and wrote it back when solar panels
were $8/watt and copper cable was cheap
. This encouraged him to use 2AWG cables
for a measly 200w of solar. Now things have changed and solar panels
are more efficient, much higher capacity, much cheaper (I've seen 59 cents/watt) and copper cables
are a lot more expensive.
Lately, I've been inclined to install more and larger panels
(if room permits) and settle for 6 AWG cable rather than 4AWG, the extra loss might be minimal compared to the output of 600w of solar vs 200w of solar back in the old days.
If the OP has any questions, we've had some great threads on solar system design, etc here on CF, or if he has a specific question, go ahead and ask it here, plenty of knowledgeable people here and there are a number of design principles that we all seem to agree on.
