Is the Hyderabad weather suitable for solar?

To understand the Hyderabad weather is suitable for solar energy or not, let’s first understand how solar PV works. Solar panels use photovoltaic cells, which you are most likely acquainted with. The Photovoltaic systems on a solar array collect the energy from the sun’s rays as it falls on the panel. In reaction to an intrinsic electrical field within the cell, this energy generates electrical charges which result in the generation of electricity, which in turn powers homes, apartments, offices, schools, and more.

Factors that Affect Solar Energy Production

A solar cell, also known as a photovoltaic cell, is a machine that transforms solar energy into useful energy. Solar cell efficiency is the percentage of sunlight that can be used to generate energy. To ensure that your solar system for home is as efficient as possible, some aspects need to be taken into account.

1. Temperature

Due to a fundamental property of semiconductor materials, temperature has an impact on solar cell efficiency. As the temperature rises, it can affect the efficiency of panels. A very high or very low temperature is not ideal for solar power generation. Additionally, rainfall does not have much impact on the panels. Infact, a rains could be good for your production as it would clean the layer of dust or dirt covering the solar panel and blocking the light. 

2. Daily sunlight hours

Whether solar panels will receive sufficient bright sunshine hours is one of the key considerations when installing them. It is crucial because solar irradiance that strikes the panel directly affects how much electricity is produced. Hence it is essential to place panels in shadow free area. We ensure no shadows fall on panels between 9 am to 3 pm.

3. Intensity and angle of sunlight

Even though solar panels produce energy all throughout the day, their power output is only at its highest when the sun is shining directly on them. The angle at which sunlight strikes solar panel modules affects how much energy they can produce.  System capacity is realized when the sun’s rays are vertical or at right angles to the panels. Solar energy is reflected whenever the rays are not parallel. Normal daytime solar production peaks between 9am to 3 pm.

4. Solar panel type

Solar panels aren’t all made equal. In terms of size, the most popular home solar panels have wattages per panel that range from 360-420 watts. Solar panels of higher quality generate more power from a smaller surface area than panels of lower quality. A higher-efficiency panel could cost a little bit more, but it will generate more power from less area if your rooftop space is restricted or shading elements cannot be eliminated. More operational tasks are carried out by inverters than by any other PV subsystem. As systems become intelligent and engage with the electricity grid more frequently, these responsibilities have continued to expand.

5. Inverter technology

An inverter’s primary job is to change the direct current (DC) electricity generated by solar panels into alternating current (AC) power, which may then be used in buildings like houses and businesses or immediately injected into the grid for front-of-the-meter applications. 

6. Shading (by obstructions)

Solar shading has a significant impact on solar PV panels. The capacity to distribute energy is significantly impacted by complete or partial shading situations, which might lead to decreased production and power losses. In order to get a greater voltage and, thus, an acceptable output of energy, the cells inside a solar panel are typically linked in series. However, this arrangement has several drawbacks under shadowing. In actuality, the unit that generates the least current determines the current of all the modules in the chain when an individual solar cell is shaded. The entire series is essentially darkened when a cell is shaded. The installation thus often incorporates bypass diodes to minimize energy loss.

Is Hyderabad suitable for a solar system?

Hyderabad is one of the ideal cities in India to go solar. The moderate temperatures year-round, and availability of 280 days of good sunlight, combine to make Hyderabad an excellent place for using solar power. Hyderabad, which is located 17° North of the equator, receives a lot of sunshine. It is not surprising that there are more solar panels on rooftops in the city, given the intermittent utility supply and escalating expense of diesel fuel. A meticulously-planned solar panel installation in Hyderabad might be quite advantageous for residential, commercial, and industrial establishments.

Hyderabad receives 5.44 kWh/m2/day of sunshine on average per year, and there are about 300 days with sunshine. Solar energy produced by Hyderabad solar farms is usable AC power, and over the course of a year, energy customers pay grid tariff of Rs. 6.5-7.4 or more. For certain users, solar energy may be less expensive than grid electricity at Rs. 4.5–5/kWh or less, and less expensive than diesel power at Rs. 18–20/kWh for all consumers. The right solar company in Hyderabad can guide you regarding which solar subsidy scheme you might be eligible for.
