Why Panasonic Solar Panels ?

Panasonic is a well recognized brand name in the technology industry and the company’s expertise also extends to solar energy. Originally under the SANYO brand, the company has been developing photovoltaic technology since 1975. Panasonic Solar panels are the result of over 40 years of research and innovation and this is evident in the quality and reliability of their solar panels. They also offer an impressive 25 year performance warranty for product power output.

There are 2 solar panels in Panasonic’s HIT range, all made with monocrystalline silicon for maximum efficiency:

HIT Kuro Black 325W/330W

The Kuro is a 96 cell module designed with both aesthetics and durability in mind. Completely black, it is finished with a thick 40mm frame and can withstand a wind and snow load of 5400 Pa. The panel features Panasonic’s unique water drainage corners to promote self-cleaning of the module and minimise dust accumulation for easier maintenance and a better long-term performance. The anti-reflection glass increases the energy absorption, minimises efficiency losses and reduces the risk of cells micro cracks due to lower laminate thickness.

PANASONIC MONO PERC SOLAR PANEL 380Wp/385Wp

Panasonic innovation of mono PERC solar panel is made in India under Anchor-Panasonic brand and wholly-owned by Panasonic. PERC stands for Passivated Emitter and Rear Cell, it is available in two forms- mono and poly cells. Usually, solar cells have an emitter layer on the front surface and a black coating on the back; but PERC uses dielectric passivation film on the back of the cells. Hence, in PERC cells, the front surface absorbs sunlight while the back absorbs scattered or reflected light; this results in a higher generation of energy than their traditional equivalents due to higher light absorption and internal reflectivity.

How to choose the best solar panels


Types of solar panel

There are 2 main types of solar photovoltaic (PV) panel to choose from: monocrystalline or polycrystalline. This refers to the type of silicon in the panels and impacts how effectively they will produce energy for your home.

Generally speaking, monocrystalline panels are more efficient, last longer and look sleeker in design. The recent upgrade on these are the mono-PERC panels offered by Panasonic. However, as you might expect, these benefits come with a higher price tag than their counterparts. Most professionals will recommend that you opt for monocrystalline, but mono-PERC could still be an effective option if you’d rather keep costs to a minimum.

In terms of aesthetics, monocrystalline panels tend to be black in colour (which many homeowners find a more attractive option) and polycrystalline are blue. You can opt for photovoltaic panels which are attached to frames and sit slightly above the roof, while others can be integrated with your tiles so they blend in more seamlessly.

Efficiency

The efficiency of your solar panels is one of the biggest factors to consider. The higher a panel’s efficiency, the more energy it will generate for your home.

When comparing efficiency remember to look at ‘module efficiency’ rather than ‘cell efficiency’. The efficiency of the individual cell will be a higher number but doesn’t represent the overall capacity of the solar panel. Modern solar panel efficiency usually sits between 16 – 20%. A solar panel with an efficiency of 19% or more is what you should be looking for, but they are more expensive.

However, you should also consider the size of your roof. If you don’t have very much roof space then you’ll need to buy a small number of the most energy efficient panels you can afford. But if you have a large roof, you can install more panels of a lower efficiency which may enable you to reduce your upfront costs.

Warranty

As with any warranty, the longer the manufacturer is willing to guarantee their product for, the more confidence you should have in its quality. In the case of solar panels, they come with 2 types of warranty period:

  • Product Warranty: This guarantees the workmanship and manufacturer’s components. If your solar panel breaks during the product warranty period they should repair or replace it at no charge. These range from 10 – 25 years.
  • Power Warranty: This refers to the length of time that the solar panels will continue to produce energy for and how effectively it will do so. For example, most manufacturers will guarantee that your panels will generate electricity at a minimum of 90% of its capacity for 10 years and 80% for 25 – 30 years.

Power Output

The higher the power output of your solar panels the more electricity it will supply your home with. The power output is measured in watts (W) and generally domestic solar panels range from 300 – 400W.

Solar panels with an output of 380W+ are the best choice if you want to generate all (if not most) of your electricity with them, but these will be more costly to purchase but they can still significantly reduce your energy bills and carbon footprint.

Reviews

You can often get a good overview of a brand’s reputation by browsing through online forums and consumer review websites.

Don’t underestimate the value of good old fashioned word of mouth. As solar panels have become more affordable they are becoming a more popular choice among homeowners, so the chances are you’ll have family or friends who have their own. Which brand did they choose? Were there any problems during installation or since? Have they noticed a significant drop in their energy bills?

Once you’ve identified a few brands you’re interested in, the next step is to contact some approved installers in your area. They’ll be able to assess your home, lifestyle, energy requirements and give you a bespoke quote. Get quotes for solar panels now.

Cost

On average, a solar panel system costs around Rs 8500 to Rs 9500/-. The cost will be impacted by the brand, type, power output and efficiency of the panels

However, when you are considering the upfront cost of a solar panel system it’s important to factor in the long term financial benefits, brand and warranty and country of origin. Generating your own electricity will mean a significant drop in your energy bills.

4 reasons to install solar panels


1. You’ll save money on your electricity bills

Generating energy for free with your own solar panels means you’ll need to buy less energy from your supplier and you should quickly see a reduction in your bills.

2. You’ll reducb your carbon footprint by using renewable energy

Unlike standard electricity the production of solar electricity doesn’t require the burning of fossil fuels and solar panels don’t emit carbon into the atmosphere.

3. You’ll be generating energy all year round – even on cloudy days!

While solar panels are obviously more effective during the summer when there are more hours of sunlight, solar panels will also be generating energy on cloudy days so can contribute to your home’s energy supply all year.

4. You can lessen your reliance on the National Grid

Generating energy from solar panels takes you several steps closer to independence as you need to buy less and less electricity from your supplier. If you also install a solar battery storage system, you can keep hold of solar electricity you’ve not used during the day for use at night which is yet again another step closer to energy freedom and increase the money saved on energy bills.
