A 300W solar panel needs at least a 100ah battery to draw 1000W. A smaller battery is enough if you are drawing the power for a short period, but a bigger battery is needed for a longer current draw.
300W solar panels can run TVs, laptops and various appliances, so no wonder it is in demand in homes and RVs. Of course a solar panel doesn't work alone, and you need a battery to reserve energy. But how many batteries will you need? A 300W solar panel needs at least a 100ah battery to draw 1000W.
Let's say you get 1500W of sunlight from your 300W solar panel (ideal weather). A 125ah battery will draw 1500W for an hour. A 6.5ah battery is enough for 1500W for 30 minutes (125 / 2 = 6.5). You can slow the discharge rate by reducing the inverter load or drawing power for brief periods only.
Example: A 300-watt panel can produce 300 watts of power per hour under optimal sunlight. The amount of energy a battery can store and supply. Example: A battery with 10 kWh capacity can power a 1 kW device for 10 hours. The duration for which a battery can supply energy without being recharged.
In a perfect world a 300W 12V solar panel will generate 1200W (300W x 4 hours of sunlight = 1200). But during those four hours, the sun's angle will change, the intensity will vary, clouds may pass by etc. If you factor these in, the average output is going to be 270W-280W, or 1100W with four hours of sun. 280W x 4 = 1120W
