Does a 300W solar panel need a battery?
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.
Do you need a battery for a solar panel?
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. 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.
How much solar power do I Need?
So, a 150Ah lithium battery or 250Ah AGM battery would be suitable. To recharge your battery daily, divide your energy needs by average sun hours (e.g. 5 peak sun hours/day in most of Australia): Solar Panel Wattage = Daily Wh ÷ Sun Hours 1490 Wh ÷ 5 hrs = 298W ✅ So, aim for at least 400W of solar to replenish your battery daily.
How much sunlight does a 300W solar panel Draw?
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.
