不——太阳能电池板没有阳光就无法发电。锂电池组可以储存白天的能量，供夜间使用。 Mars Solar 套件包含的磷酸铁锂电池，在 95% 放电深度下可循环使用 6000 次以上——足以满足大多数家庭夜间用电需求。
Yes — full terms are published online. Mars panels: 25-year linear output warranty. Lithium battery, hybrid inverter, and charge controller: 2 years. Lightning damage excluded — we recommend surge protection devices.
Yes — and most of our customers do. Mars Solar 10KVA hybrid inverter supports battery expansion up to 30 kWh and panel array growth without inverter swap or rewiring. Share your 5-year plan at the design stage and we'll oversize from day one.
Select grid-tied, off-grid or hybrid inverters per local voltage & frequency. Choose IP65 wide-temperature units with multi MPPT. Models support wide voltage fluctuation; prepare local certificates for customs clearance.
In most cases, yes — but far less than before. A 10 kW solar system array drops from 50-60 kWh/day in summer to 35-50 kWh in winter. Hybrid and fully off-grid systems can eliminate or drastically reduce grid dependence. Mars kits support all three configurations.
Choose LiFePO4 for 6,000+ cycles at 95% depth of discharge. Size as: daily kWh x days of autonomy x 1.1. Use 48V for residential efficiency. Battery box must be IP65+ rated with built-in BMS.
Focus on wattage (590W for space efficiency), efficiency (23%+ for constrained roofs), temperature coefficient (-0.30%/C or better for hot climates), and a 25-year linear output warranty. Monocrystalline PERC panels are the best choice for most systems.
Most homeowners underestimate by 20-30%. Quick rule: monthly kWh / 30 = daily use, then add 10-20% for winter drops and 5-10% system buffer. Most Philippines and Nigeria off-grid homes need 10-30 kW solar + 15-60 kWh battery.
