What is a solar rooftop system?
A solar rooftop system is a combination of many components that convert sunlight into usable electricity.
The components of a rooftop solar include the following -
| Component | Description |
|---|
| Solar panels with PV cells | Collect sunlight and convert it into DC electricity. |
| Solar inverter | Converts DC electricity into usable AC electricity. |
| Solar panel mounting structures | Supports the panels on rooftops. |
| AC & DC cables | Carry the electric current. |
| AC & DC combiner boxes | Combine and protect the wiring from multiple strings of solar panels. |
| Earthing cables, Connectors | Provide grounding for the system. |
How does a solar rooftop system work?
A solar rooftop system works on the concept of conversion of sunlight into electricity. The phenomenon is known as the photovoltaic effect. When sunlight falls on the PV cells in a solar panel, the sunlight is converted into electricity. The generated power is DC current. An AC combiner box is used to convert that DC power into usable AC power. The generated AC electricity is fed into a bidirectional meter that supplies power to the house. It also exports excess power to the electricity distribution company – DISCOM (such as PDB, DESCO, DPDC, REB, NESCO etc. or gird) and imports power from the grid if electricity generated by the rooftop solar system is not enough to cover the daily requirement.

Why should I go solar?
If you want to save money from the sun, Solar is the best investment for you. Solar allows you to save on your monthly electric bills plus it also allows you to save the planet by going green. Solar energy is a true form of renewable clean energy which leads to zero pollution (air, noise, land) and emits no greenhouse gases, thus mitigating climate change.
Is solar power safe?
Yes. The electricity produced by a solar power system is no different than the electricity you get from your electricity distribution company. The only difference is the source. Moreover, it is among the safest source of electricity consumption because it is neither hazardous nor does it release any toxic or harmful gases during production.
What do I need to install a rooftop solar system?
All you need to qualify for a solar system is - empty space on your rooftop and access to it. Just fill the project enquiry form on our website and our team will contact you to discuss your requirement. Once the project is finalized, we will take care of your entire plant design, installation and maintenance.
What are the different types of Solar systems?
There are 3 types of solar systems depending on whether the plant is linked to the power grid or battery systems for storage:
- On-grid solar systems: Use common solar inverters and are connected to the public or government national electricity grid. Any excess solar power that you generate is exported to the electricity grid, and one usually gets paid a feed-in-tariff or credits for the energy you export. This policy is called the “Net-Metering Policy” and is available currently in Bangladesh.
- Off-grid solar systems: These are not connected to the electricity grid and therefore require battery storage. The system must be designed to generate enough power year-round and store enough battery capacity to meet home requirements, even in winter with less sunlight.
- Hybrid solar systems: Combine solar and battery storage in one and are available in different configurations. This allows you to store energy generated during the day for use at night. When stored energy is exhausted, the grid provides backup.
Do solar panels generate electricity even during monsoon and winter?
Yes, solar panels do produce electricity in cloudy or rainy weather but with reduced efficiency. This fall in production is accounted for in the unit generation estimates provided for every project.
Does a rooftop solar PV generate power during a power failure?
No, rooftop solar PV does not function or generate electricity during a blackout due to safety reasons. Since blackouts occur when the electricity grid is damaged. If a solar inverter was still feeding electricity into a damaged grid, it would risk the safety of the people repairing the fault in the network. Dyadic Solar Energy provides the option of using a Li-ion storage battery with Solar power plants for areas that suffer from frequent power failures. This battery unit can store the excess electricity produced during the day and acts as a backup for any electricity requirement during the night or in the event of a power failure.
How much electricity does a solar plant produce?
The production level of a solar plant depends on multiple factors like radiation levels, amount of sunlight received, plant design, and quality of components. On average, a 1 kW solar plant produces 4 units of electricity per day.
What kind of appliances can I use on Solar Power?
Solar Power plants are used to power all types of heavy machinery in industrial plants as well as household electrical and electronic appliances. Since the electricity produced from the plant is fed in sync with your grid/diesel generator, there are no voltage fluctuations irrespective of the number of appliances you use.
How do I decide what size of plant I need?
The size of your Solar plant depends on the following factors:
- Your electricity consumption pattern
- Available shadow-free area
- Solar radiation in your area
Once you enlist your interest in a solar project, Dyadic Solar conducts a scientific mapping of the appropriate project size for you.
What is Net metering?
Net Metering is a system that gives solar energy owners credits for the power that they add to the grid. When solar panels produce excess power, that power is sent to the grid. And this power can be ‘taken back’ when the solar plants are not functioning – for example, during the night. When a unit of solar energy has been ‘net metered’, the bi-directional electricity meter will run backwards. Customers are billed only for the ‘net’ energy use.
