Assessing your energy needs

Before installing a solar power system, you must determine your energy needs. Analyse your past electric bills to determine your average monthly kWh consumption. From this analysis, you can select the size and capacity of your solar system to meet your energy needs.

Assess the Suitability of Your Roof

Make sure your roof is suitable for solar panel installation. Assess its condition, orientation, and slope to determine its solar potential. Ideally, a south-facing roof with minimal shading is optimal for maximum solar energy gain. Also, check the structural integrity of your roof to make sure the solar panels’ weight won’t be too much for it.

Calculate the available space

Measure the available roof space to determine how many solar panels can be installed. Consider any obstructions, such as chimneys or ventilation systems, that might limit the public space. Each solar module requires a specific area, so it is essential to consider the dimensions and spacing of the modules for an accurate calculation.

Determine your budget and financial capabilities

Set a budget for your PV system and explore financing options. Find out about payment options such as prepayments, loans, leasing, or power purchase agreements (PPAs). Learn about available financial incentives, such as net metering and feed-in tariffs, which can significantly impact the return on your investment.

Choose the Right Solar Installer

A good installation depends on picking a reliable and skilled solar contractor. Research the market and get quotes from several installers to compare prices, warranties, and customer reviews. Choose a licenced installer who can provide a detailed quote and answer all your questions.

Choosing the right PV System

Consider what type of PV system fits your needs. You can choose between grid-tied, off-grid,, or hybrid systems. Grid-tied systems are connected to the power grid, making it possible to recycle surplus energy. Off-grid systems are independent and not connected to the grid, while hybrid systems combine the advantages of both approaches.

Obtain required permits and approvals

Make sure you have obtained the necessary permits to install the solar system. Check with your local authorities and utilities for their policies and procedures. This may include building and electrical permits, connecting the approach to the grid, and complying with safety regulations.

Research available incentives and subsidies

Find out what incentives and subsidies are available for solar installations in Bangalore. The central and state governments often offer financial incentives such as subsidies, tax credits, and low-interest loans to encourage the adoption of solar. Check out these programmes to find out if you are eligible for them and how they can help lower the cost of installation.

Review Maintenance and Warranty Services

Review the maintenance requirements and warranties offered by the installer and manufacturer. Find out what maintenance is required and if the installer offers ongoing support. Review the warranty terms for the solar panels, inverters, and other components to ensure they are consistent with industry standards.


Installing a solar system in Bangalore can provide numerous benefits, from financial savings to environmental sustainability.
