Is it worth installing solar panels in my house?

[telling]

Is it worth installing solar panels in my house to power all my electrical equipment and completely cutting off power coming from the grid, keeping in mind the initial investment and long-term savings? This website review says that If you completely cut-off from grid, then you will be needing batteries for storage.And batteries not only increases cost of project but they need to be replaced after 4-5 years plus its maintenance. Instead, go for net- metering.You can enjoy all electricity generated by panel during day time and during night time, you can fetch power from grid. In case you consume more than you generate, you have to pay for excess units.
