Off Grid Home Solar System Application Guide
Are you a wholesaler or installer? Either way, it would be a great endeavor to build a house solar system for your customers so that the house has 24/7 power.
Advantages of Off Grid Home Solar System
No grid dependence, precisely targeting the market of remote households that lack electricity; energy storage batteries to extend the power supply time and reduce after-sales costs; policy subsidies (tax breaks, installation subsidies) to lower the terminal price and enhance product competitiveness; modular design to adapt to a variety of household scenarios, rapid installation to seize the market. For channel operators: high gross profit (20%+), long-term re-purchase (equipment upgrades + accessories), leveraging on the new energy policy dividend to create a differentiated product line.

How to build a Off Grid Home Solar System ?
5 Necessary Steps 💡
1、System Planning and Site Selection
Start by assessing the home’s electricity needs and determining where to install the PV modules (roof/yard). Ensure that there are at least 6 hours of unobstructed sunlight per day and reserve enough space for the solar panel array.
2、Core Component Selection
Photovoltaic module: choose the appropriate power solar panel according to the power consumption (20% reserve is recommended)
Controller: MPPT controller that matches the system voltage to ensure efficient power regulation (Our solar inverters have built-in MPPT controllers).
Energy Storage Battery: choose the special lithium battery pack for solar energy with a cycle life of 6,000+ times.
Inverter: select pure sine wave inverter according to the power demand of electrical appliances (need to cover the peak power)

System Advantages
10-year long life cycle
Average daily power generation can meet the needs of a family of 3-5 people
Saves 60%-80% of household electricity expenses
Supports off-grid/grid-connected dual-mode switching
With these five steps, you can build a reliable home energy autonomy system that will safeguard your basic power needs in the event of a power outage. It is recommended to choose UL certified components and keep 10-15% power redundancy for expansion.

Looking Ahead 🔭
In the next decade, the field will show two major trends: on the technology side, lower-cost energy storage technologies such as photovoltaic (PV) tile roofs and sodium-ion batteries will be popularized, and home systems will be gradually upgraded to “zero grid dependence”; on the application side, modular design and financing and leasing models (e.g., starting from a down payment of $999) will lower the barrier to entry, and the system will not only provide power, but will also integrate functions such as EV charging and smart home control. Although the initial investment and recycling regulation is still a challenge, with the technology iteration and policy improvement, it is expected that by 2030, solar off-grid system will become the standard configuration of new homes, and truly realize the transformation of the family from “electricity user” to “energy producer and distributor”.
