Understanding solar panel output: Standard Test Conditions vs.
The amount of power a solar panel generates under the Standard Testing Conditions becomes its maximum power rating or nameplate capacity. If a solar panel outputs 400 watts at STC, it will be labeled as a 400-watt solar panel. Unfortunately, your solar panels will rarely, if ever, experience these Standard Test Conditions.
Premium Marine Solar Panels For Boats
A 100 watt panel with high efficiency solar cells will produce up to 30% more power in a 24 hour period or 100 watts x 6.5 effective hours or 650 watt hours of power in a day. At 13 volts, that''s about 50 amp hours in a day. 38 amp hours vs. 50 amp hours in a day is significant on a boat (or van or RV). Add more panels in the mix, say 400 watts ...
