Solar Power for Home or Office

In India solar revolution has started, Many Residences using solar power for their homes and saving a lot of money every month.  Now the advantage is, solar panel prices have slashed to very low and this is the right time to invest on rooftop solar PV.  Planning to use solar power for your requirement requires considerable investment with great emotional decision.  We at Unilet Solar in the right forefront and leading towards renewable energy solutions  with great infrastructure to serve our customer requirement.   Using solar power leads to great savings as well as saving environment.

Monocrystalline Advantages:

  • Mono solar panels have the highest efficiency rate (usually around 15%-20%);
  • Monocrystalline modules are space-efficient. Because these modules deliver the highest power output, they require the least amount of space comparing to other solar panels;
  • Mono solar panels have a long lifespan – most manufacturers offer a 25-year warranty on their mono solar panels;
  • They perform better than other types of solar modules in low-light conditions.


  • Monocrystalline modules are the most expensive;
  • If they are covered with dirt, the entire system may be affected;

Polycrystalline Advantages:

  • The process used to manufacture poly solar panels is simpler and, thus, less pricey.
  • They usually have a lower heat tolerance than monocrystalline modules.


  • Because the silicon purity is lower than mono modules, poly solar panels are less efficient than their mono counterparts. Their efficiency is usually rated at around 13%-16%.
  • Not only that they are less energy efficient, but they have a low space efficacy as well. You need to cover a larger surface to get the same power as you would with monocrystalline modules.

So, which is better?

The answer depends on your project’s specification. Poly modules, for instance, are ideal for projects with large roof or ground space. They are also great for consumers on a tight budget who are looking for ways to keep installation costs to a minimum.

Mono solar panels, on the other hand, are perfect for small roofs or space-constrained properties. Since monocrystalline modules are very efficient, you will get more power onto the same surface area. Moreover, these panel types have a lower temperature coefficient than poly modules.

Monocrystalline modules are more expensive than poly modules, but they take up less space. For instance, if you have one mono and one poly solar panel, both rated at 240-watt, they would generate the same energy, but the monocrystalline solar module would take up less space.

If cost is your major concern and you want to pay as little as possible for installation, then you should opt for poly solar panels. You won’t get the same efficiency as with monocrystalline modules, but you’ll reduce the initial costs dramatically.

What is the difference between On-grid and off-grid solar power?

On-grid means your solar system is tied to your local utility’s GRID. This is what most residential homes will use because you are covered if your solar system under or over-produces in regard to your varying energy needs.

off-grid means you are not connected in any way to your grid’s power system or utility company. This is appealing because you are 100% self-sustaining your energy use. However, there are disadvantages because off-grid systems require you to purchase back-up battery which can be expensive, bulky, and not very environmentally friendly which defeats the purpose of going solar (save money and live greener).
