What is the Maintenance Cost of Solar Panels?

Hey Pal,

The solar panel maintenance cost is influenced by the brand and kind of solar panels installed (monocrystalline vs. polycrystalline), as well as the installation method (shed mounted, ground mounted, RCC mounted).

.

The following variables affect how much it will ultimately cost to build a solar system:

varieties of solar panels:

• The cost of the solar system will rise if monocrystalline solar panels are used because they are more expensive than polycrystalline solar panels.

• Placing solar panels on an existing metal shed is less expensive than installing them on RCC with elevation. The expense of the system increases as you perform more elevation.

• The cost of the system would be expensive if you choose premium solar panel brands. Going with less expensive brands may allow you to save 5% to 10% up front, but the generation will be lower and you will ultimately lose more money as a result.

• The price per kilowatt increases as the system size decreases. One kW of solar power will cost Rs 80,000 per kW, whereas 100 kW of solar power will cost between Rs 45,000 and Rs 55,000 per kW.

The cost of polycrystalline solar panels for premium brands like Vikram, REC, Renewsys, and Waaree ranges from Rs 19 to Rs 30 per watt.

Monocrystalline solar panel costs for high-end international companies like Panasonic, REC, Longi, and Trina range greatly from Rs 32 per watt to Rs 50 per watt.

The cost of maintenance is minimal if you plan to construct a solar on grid system because it doesn't require batteries and all other parts, such as solar panels, solar inverters, distribution boxes, AC, and DC cables, can last for 15 to 20 years with little to no upkeep.

You will need to perform routine maintenance on your solar panels since dust can accumulate on top of them, blocking sunlight from reaching the solar cells and reducing electricity production.

However, because solar off-grid systems involve batteries, your home solar maintenance costs will be significant if you decide to install one. Because batteries lose storage capacity over time (depth of discharge decreases) and discharge rates rise, every battery needs to be replaced every 3 to 5 years.

To give you a general idea, Exide tubular solar batteries sell for about Rs 18,000 per unit. Therefore, if your system has 4 such batteries, the cost of replacement will be close to Rs 70,000.

The cost of solar system maintenance ranges from Rs 1,000 to Rs 3,000 per kW. The cost per kilowatt decreases with system size and vice versa.

I would like to conclude here about the solar panel maintenance cost. I hope this helps:)
