Many people around us are seen shifting to solar energy nowadays — primarily due to its cost effectiveness, durability, reliability and eco-friendliness. Besides, the installation of solar systems is quite hassle-free too. The biggest issue one might encounter while switching to solar energy is choice of the best solar system. For making a long-term investment in solar systems, you must research well and take account of all the features with the pros and cons of each. The two most commonly used solar systems in recent times are:
For a better understanding of these systems, below is a comprehensive detail of both of them. After going through it, you can decide which one suits you the best on your own—based on your requirements and preferences.
This solar system is widely known for residential and commercial usage. On-grid solar system is commonly referred to as on-tied solar system. Its working methodology is briefly explained below
This solar system has a direct connection with the grid. On-grid solar system does not need batteries for its functioning. It operates by converting the solar energy into DC power. The home appliances don’t run by DC energy—so on-grid solar inverters are used for converting this DC power into alternating current which in turn is utilized by all electrical instruments at home.
The excessive energy that is not utilized goes back to the grids connected to the on-grid solar system. This solar system allows its consumers to utilize net-metering— by which its users can export surplus energy than their home requirements to the public grids and in turn get paid by the feed-in-tariff (FIT) mechanism by following net metering policies that vary in different regions.
Now, let’s have an insight into the advantages of the on-grid solar system:
A few disadvantages of the on-grid solar system are
Hybrid solar systems has the below described characteristics and working criteria.
In a hybrid solar system, there is energy backed by the batteries and solar panel is connected to the grid. It is primarily intermediate in between off-grid and on-grid solar system as it contains battery backup like the off-grid system and is connected to the grid just like on-grid solar system. The only difference is that hybrid PV system is not entirely dependent on the grid for its functioning—unlike on-grid solar system.
It starts using energy from the grid instead of solar batteries during the evening and night times —thus acts just like the regular UPS.
One can recover the investment of expensive hybrid PV system due to a vast range of its advantages listed as
To summarize, the basic working methodology of both systems is quite similar— be it hybrid or on-grid solar system. Both of them convert the solar energy into DC power that is in turn converted to AC power by inverters which is utilized to run different home appliances. The basic difference is the storage of excess energy to be used at times of no solar energy input, which is stored in batteries in hybrid systems and is exported to grids (in turn providing credits to its users), in case of on-tied solar systems. Hybrid systems are better in terms of reliability while on-grid solar systems are a plus for people on a budget. You can select which solar system would be better for you— as per your needs, after going through this comprehensive explanation of both systems.
Because they come with battery backups. The combined cost of solar batteries and hybrid inverters make hybrid solar system expensive compared to on-tied solar system which lacks batteries.
These solar systems have batteries in which excess energy is stored. At times of no solar input energy, they isolate the whole solar system from the grid and utilize the energy stored in solar batteries to run the home appliances (called islanding).
You probably are not saving despite going solar— firstly because your utility company does not provide user-friendly net metering policies.
Secondly, shade by large number of trees on the roof can also reduce solar power and in turn electric output. Installment of lesser solar panels due to smaller roof size can also minimize power output — thus it won’t cut down much of your bills.
Certainly yes! A large amount of daily solar input and the correct choice of PV plates, solar batteries and inverters are a few factors that can help for powering an entire house with solar energy.
