How to save 35% or more on your electricity bills

Are you facing an energy crisis and high electricity bills? Do you care about a clean environment and eco-friendliness?

Energy consumers in the residential segment face nagging energy-crisis during the summertime. With the energy unit costs rocketing day by day, it is nearly impossible for the consumers to cut their down high electricity bills. So, what are the options for the consumers that are feasible, practical and renewable?

Residential Solar Installation

Harnessing solar energy is a cleaner and renewable source of energy that could fend-off energy crisis and save 35% or even more on monthly electricity bills. With the advent and widespread usage of solar energy, K-Electric has introduced Net-Metering, Reverse Metering or Grid-Tied Solar Systems. Net-Metering enables consumers to sell back excess power back to the grid and the units exported are credited in next month’s electricity bills.

Tips to choose between On-Grid & Off-Grid Solar System

An on-grid solar system also referred to as grid-tied solar system runs directly from the grid (K-electric. KE installs a special Smart Meter at the house for the monitoring of the export and imports of units. This is ideal for houses where power supply from the grid is constant and there is barely any load-shedding or power cut-offs. The primary benefit of an on-grid system is you do not need a battery bank, which is a hefty cost of the total proposition. Conversely, the system does not generate electricity if power from the main grid is switchedoff.

Off-grid system, on the other hand, uses a battery bank. In the daytime, the house runs directly from the sunlight converted to alternate energy (AC) while the unused power is saved in the battery, which can be used at night and at the times of load shedding.

Advice for choosing between Monocrystalline & Polycrystalline Solar Panels

To keep it simple and less technical monocrystalline panels appear as one flat-color while polycrystalline panels have a blue-hue. Mono panels tend to have greater efficiency than poly and are a bit expensive options. These are also the oldest and most produced panels.

Polycrystalline panels are a newer technology; these panels tend to have a slightly lower efficiency than mono and have a comparatively low cost.

Regardless of which panels are preferred, it is pivotal to go for a good quality brand and manufacturer. A brand that has a reputation and is known for superior quality.

How much space is required and what should be the ideal system size?

1kW of solar system requires approximately 120-140 sq. ft. of space. The size of the system varies as per the purpose and consumption. If you are consuming 650-700 units a month, a 5kW would be ideal for you, which generates the same amount of units a month (approximately) equivalent to saving about Rs. 10,000 monthly. 10kW systems generate approximately 1400-1500 units a month, with estimated savings of Rs. 20,000.

These systems might appear to have a high up-front cost but it starts saving from day 1 and the system pays back the total cost within approximately 2-3 years.

Do solar panels offer safety and resist wind?

Solar panels can be installed on a rooftop or ground with an aluminum, galvanized iron, and mild steel structure. These structures can withstand winds up to 30-35 k/h. Solar panels installation are safe and the structures are built to endure in almost all conditions.
