How To Choose The Best Solar Water Heaters In India? (Buyer Guide)

Solar water geyser is a relatively new concept for us, and hence we must pay attention to certain factors before buying one. Here are some buyer tips which will come in handy while purchasing the best solar water heater for your home:

1. Usage of Hot Water:

Before buying a solar water heater for your home, think of the Return on Investment (ROI). The initial set of a solar water heater is quite high compared to an electric or gas water heater. Small families who seldom use hot water may not reap benefits from this installation. Medium and Big size families who use large amounts of hot water for their daily needs will enjoy better savings with a solar water heater. So, keep your usage in mind before investing in a solar water heater.

2. Design of your House:

The design and location of your home are important factors to reap the maximum benefits of a solar water heater.

  • The roof of your house should receive at least 6-8 hours of direct sunlight and has enough space to place the solar panels. If you don’t have access to a roof, then make sure you have an open space, like a balcony or sit-out, that receives constant sun exposure.
  • You must select a spot on your roof or balcony which has the best sun performance. Experts recommend True North or true south for the best energy production.

3. Different Types of Solar Water Heaters:

There are two types of solar water heaters you must know about – Active and Passive. You can make a selection of these two types, based on the climate of your area.

  • Active Solar Heaters: Active solar heaters are suitable for areas with colder climates and have an indoor water tank to prevent the water from getting frozen. They are quite efficient but require special equipment and higher setup costs to pump hot water.
  • Passive Solar Heaters: Passive solar heaters are quite economical and do not require any special equipment or elaborate setup. Instead, they directly channel the heat of the sunlight to produce hot water into storage tanks or to your showers. These solar water heaters are ideal for areas which receive at least 300 days of bright sunlight in a year.

4. Size of Solar Water Heater:

You can decide on the size of the solar water heater based on your usage needs. If you are planning it use for commercial purposes, like a hospital or a hotel, go for a minimum 500 litres capacity heater which also comes with large solar panels. For residential purposes, a water heater with 100 litres capacity will fulfil the needs of a large family.

5. Budget and Subsidies:

Solar water geysers require a high initial setup cost, which can range between Rs.15,000 to Rs.50,000 or above, depending on the brand and the features. However, our government offers subsidies and rebates to encourage your environmental-friendly decision. Make sure that the brand and model you choose offers better ROI by enquiring about its maintenance cost, life expectancy and overall annual savings.
