Pakistan’s solar surge: a new era of affordable, scalable energy

Photovoltix (PV), the ability to transform sunlight directly into the power of lightning anywhere on the planet, has turned human life into good. Just 12 years ago, there was no PV system installed in Pakistan. The first solar power plant near Bahawalpur was bravely launched in the midst of some public doubts. Now the PV system can be found nationwide, which provides electric electricity during the day for agriculture, households, factories and joint grid. This is just the beginning of how the renewable energy source can change the country’s economic fate.

What is a PV system?

One PV system contains three essential ingredients: solar panels, alias APV module, an inventor, and growing. The solar panel contains a semiconductor (usually the second most abundant element of the earth) that absorbs solar energy to convert external use into electric electrical power. The physics of how the solar panel works is primarily similar to the photo synthesis. Inverter, the system’s brain operate, controls a combination of solar panels to supply power power for its desired use. Inverters can ramp up and down the power power, fix the power quality, and shield it for grid or off grid application. The mounting solar panel is held so that it is available for the available space, the maximum angle toward the sun, and the thermo is mechanically stable to change the situation. A well -designed, made, and maintained PV system can provide a guaranteed power schedule for at least three decades, which is less than half a percentage of its initial production every year. Other power parts such as cables, transformers and switch gear, are also important because for any electric power delivery system connected to the grid.

The beauty of the PV system lies in its modification and scalebuability. This system can be deployed between ceilings, backyards, agricultural crops, wider barren fields, hills, or water reservoirs, even in the open sea (mounting design and material has been shielded). No other source of electricity goes for humanity offers to make such a democratic empowerment.

Economy and quality

PV is the cheapest source of electricity around the world during the day, even in low sunshine places in the highest levels. No fuel is required for power generation, so once successfully commissioned, solar power costs are fixed for a long time. The basic PV system kit’s turning capital cost depends on US-day space, grid connection requirements, and revenue on import components, these days can start with minimum of USD30O/- per kW. The cost of power generation will depend on the sunshine of the location and any financial support. It is almost always cheaper than other sources of electricity on the grid. In this place the change of sunshine can be predicted for a long time, which is estimated at the energy production simulation, and is priced in the purchase of solar energy. Therefore, it is the most economic and cost -effective shape of electricity.

This unbeaten economy of PV Power cannot be taken with appreciation. This system depends on design and installation quality. The key components of panels, inverters, mounting, must be carefully selected for the deployment of the system. Particularly in the panels, hidden or lukewarm defects, can be the result of chronic low performance after a few years or more disastrous consequences of electricity fire and premature system malfunction.

To reduce these risks, the solar buyer needs to take quality control measures from factory production to factory to installation to installation, including imaging of a panel for defects that do not see the human eye. Can Various thermal, mechanical and increasing tests of chemical pressure have to be verified. The emissions of warranties, and responsibility, have to be understood for every component. This kind of diligently small to medium -sized PV system is the clutter for ordinary public buyers. A Public Service Bureau is recommended for free advice on buying and using PV systems. In addition, this solar service bureau buyers have been obsolete, compared to their use, sophisticated technologies, the best methods, and on the overall system design reservations for fair legal terms for purchase transactions. Could advise buyers. This service will be mutually beneficial for private solar buyers and public power regulatory authorities.

Grid Support and Virtual Power Plants

Solar PV is an interruption technology. Legacy power suppliers, their market positions and business relations, are worried about the industrial appearance of this new power through. Therefore, it is not surprising that many misinformation spreads publicly to its development, to try to empower and slow itself. Once the argument is that the PV weakens the grid, can cause it, and the distribution grid can run companies into bankruptcy. It is against the truth of the matter.

The power of the grid depends on maintaining its fixed frequency and voltage in all places – the former has to do with active or useful power, and the latter, called the reaction power. Although active power can be brought to a long distance of transmission and distribution lines, this is not a matter of reaction power. The more distributed electric electricity than the PV system enables local delivery points, which is more controlled by the strength of the grid network. Inverters can inject and absorb the power of the reaction, thus increasing the voltage stability of the grid.

The physical method of power losses in the power grid lines is the opinion resistance that increases in proportion to the power delivery distance. Distributed PV systems can reduce these distances. Voltage drops in the grid also increase power losses – the inverters reacting strength is less than the ability to react. These benefits strengthen the grid instead of weakening, providing intelligent distribution grid companies more and more means to overcome their power losses and supply quality.

Solar capacity has been extended to the evening hours, with the possibility of economically storing it in electrochemical batteries. These batteries are also a modular and expanding technology. Battery prices decreased from the lithium -ion battery unit for the last year by lower than kg watts per kg (in terms of energy transfer speed, the full price of the battery system starts three to four times more than the unit cost. Are).

So far, private PV systems are being installed in Pakistan without any viable coordination. Distribution grid operators allow pure measurements, but there is no overall control over how the individual PV system can be made to work in alliance. With the latest technology, the solo PV system can be run as a huge power plant spreading to various locations, but serving the grid as it is a stable virtual power plant of several Gigwat electricity capacity. Virtual Power Plants are being successfully deployed all over the world. This possibility will take the country’s solar capacity and its grid support to the next level. This requires more modern cooperation between the regulatory regulatory officials, grid operators, consumers, and the international solar pulse storage industry to expand the Pakistan market.
