How much would an off grid solar system cost?
Off-grid solar systems are available in a variety of sizes for a variety of purposes, including small homes, 2-3 floor homes, shops, offices, schools, warehouses, and more. The lowest range of an off grid solar system is 500W, the average range is 1kW, and the maximum range can range from 3kW to 10kW. Simply said, the cost of a 1kW off-grid Solar System with a Single Battery (12V) is around Rs. 80,000, whereas the cost of a 1kW Off Grid Solar System with a Double Battery (24V) is approximately Rs. 100,000. The cost of any solar system is determined by factors such as technology, brand, service, and warranty.
Off-Grid Solar System types- AC or DC coupled types-
Off-grid systems can be powered by either AC or DC connected power sources. Common AC-coupled generating sources include solar inverters, wind turbines, and backup generators (gen-sets), whereas DC-coupled sources include MPPT solar charge controllers and micro-hydro systems.
The size of the system determines whether the system is AC or DC linked. The majority of small-scale systems under 6kW are DC linked and employ efficient MPPT solar charge controllers. Larger off-grid systems can be AC or DC linked, depending on the kind of inverter-charger utilised and compatibility with various solar inverters (AC) or solar charge controllers (DC). Most current multi-mode inverters may be both AC and DC linked, resulting in a very secure, flexible power system with numerous charging choices and the ability to perform a black-start operation if the primary inverter fails, the backup generator fails, or the batteries are exhausted.
Small DIY Off-Grid Systems-
MPPT solar charge controllers, also known as solar regulators, are used in small-scale off-grid solar systems and DIY systems used on caravans, boats, tiny residences, and cottages. They are linked between the solar panel/s and battery. The charge controller's function is to ensure that the battery is charged appropriately and, more critically, that it is not overcharged. The load output terminals on most modest 12V/24V solar charge controllers are frequently utilised for basic DC lighting circuits. Simple 'plug-in' type inverters are used in modest DIY systems to provide 240V or 120V AC power. These are available in a variety of capacities, ranging from modest 150W inverters to 3000W or greater.
Important factors to consider when estimating off-grid solar systems-
- Daily average energy consumption (kWh) - Summer and winter
- Peak load (kW) - The maximum amount of electricity used by loads.
- Average continuous load (kW)
- Solar exposure - Location, climate, orientation & shading
- Options for backup power - During inclement weather or a power outage
The primary battery inverter-charger, often known as a multi-mode inverter, since it can typically function in both off-grid and on-grid modes, is the fundamental component of an off-grid power system.

Is 1 kW enough to run a house?
A 1kW solar system can easily power a 2-3 BHK house wherein you can use one refrigerator, three fans, one TV, one laptop, and 4-5 lights. On average, you can run about 800 W loads on a regular basis.
How many AC can run in a 5kW solar system?
2-3 ACs
A 5kW solar power system is sufficient in supporting the electricity needs of a 2BHK, 3BHK and any other medium-sized houses with 2-3 ACs. It is a medium-capacity solar system for homes that has the capacity to generate up to 20kWh (units) of electricity.
Is off-grid solar worth it?
In areas with frequent power outages or unreliable grid connectivity, on-grid systems may not be the most suitable option. In such cases, off-grid solar systems with battery storage can provide a more reliable and independent source of electricity.
How much is a 6.6 kW solar system?
$5,000 to $7,000
A good quality 6.5kW or 6.6kW solar system will usually cost in the range of $5,000 to $7,000. You can buy cheaper components such as panels and invertors and that will save you money on the initial outlay but you will probably spend that money many times over with short equipment lifespans and expensive repairs.
