how human eye works

The human eye is an organ that allows us to see. It does this by detecting light and converting it into electrical signals, which are then sent to the brain. The eye is made up of several parts, including the cornea, the iris, the pupil, the lens, the retina, and the optic nerve.

The cornea is the clear, dome-shaped surface at the front of the eye. It helps to focus light as it enters the eye. The iris is the colored part of the eye that surrounds the pupil. The pupil is the black circle in the center of the iris, and it adjusts in size to control the amount of light that enters the eye.

The lens is a clear, flexible structure that sits behind the pupil. It helps to focus light onto the retina, which is a thin layer of light-sensitive cells at the back of the eye. The retina converts the light that it receives into electrical signals and sends them to the brain through the optic nerve.

The brain then processes these signals and interprets them as images. This process occurs almost instantly, allowing us to see the world around us in real-time

how does kidney work

The kidneys are a pair of organs located in the back of the abdomen. They are responsible for filtering waste products and excess fluids from the blood, as well as regulating the balance of electrolytes in the body.

The kidneys filter the blood by removing excess fluids, electrolytes, and waste products, such as urea and creatinine. These waste products are then excreted in the urine, which is collected in the bladder until it is eliminated from the body through the urethra.

The kidneys also help regulate blood pressure by releasing a hormone called renin when blood pressure falls too low. Renin acts on a substance in the blood called angiotensinogen, converting it into angiotensin, which constricts blood vessels and increases blood pressure.

The kidneys also produce hormones that regulate red blood cell production and maintain healthy bones. For example, the hormone erythropoietin stimulates the production of red blood cells, and vitamin D, which is activated in the kidneys, helps the body absorb calcium, which is necessary for strong bones.

Overall, the kidneys play a vital role in maintaining the overall health of the body by removing waste products and excess fluids, regulating blood pressure and electrolyte balance, and producing hormones that help regulate various body functions.

how hybrid car works

A hybrid car is a vehicle that uses two or more different sources of power to move. Most hybrid cars use a combination of an internal combustion engine (ICE) and an electric motor.

Here’s how a hybrid car works:

  1. The internal combustion engine (ICE) runs on gasoline and is used to power the car at higher speeds or when the electric motor is not sufficient to meet the car’s power needs.
  2. The electric motor is powered by a battery pack and is used to power the car at lower speeds or when the car is stopped. The electric motor can also assist the ICE when the car is accelerating or climbing a hill.
  3. The battery pack is charged by the ICE and through regenerative braking, which captures the energy that is normally lost when the car is braking and converts it into electricity to recharge the battery.
  4. The hybrid car has a control system that determines when to use the ICE, when to use the electric motor, and when to switch between the two. This allows the car to operate as efficiently as possible and to minimize fuel consumption.

Hybrid cars offer several benefits, including improved fuel efficiency, lower emissions, and the ability to run on electricity alone for short distances.

Facts about high-efficiency Solar Panels

 

 

If you’re interested in installing solar panels on your roof, you’ll want to ensure that the PV system you choose has the highest wattage output possible. The efficiency of your solar panel depends on the surface area of the photovoltaic cells used to generate electricity.

The more cells that are present on the solar panel, the more efficient it will be. In addition, the efficiency of a solar panel is also determined by the materials used to manufacture it. For example, crystalline silicon panels have a slightly higher efficiency rate than monocrystalline or thin-film panels.

The higher the efficiency of the panel, the more electricity it produces, and the more electricity you’ll save on your utility bills. The cost of purchasing and installing solar panels is usually determined by their efficiency rating.

A higher efficiency panel will cost more initially, but it will save you money in the long run because you’ll be able to produce more electricity with a limited amount of space. For example, a standard-size500wattt panel will produce around 4,000 watts of power during its peak performance period, but a high-efficiency750wattt panel will produce approximately 6,000 watts of electrical power during the same period.

So not only will you be able to generate more power with the same amount of space, but you’ll also be able to produce more power with fewer panels since they’re able to absorb more sunlight. Shading and weather conditions can also affect solar panel efficiency. Shading can reduce the overall efficiency of a panel by up to 50% because it prevents the sun from reaching all of the cells on the solar panel.

Overcast weather will also reduce the effectiveness of a panel because it reduces the amount of sunlight it receives. However, neither of these conditions will impact the performance of your solar panels significantly if you only use one panel. You’ll still get plenty of free electricity from the sun even on overcast days, so you won’t need to rely on fossil fuels as much if you do most of your cooking, washing, and other household chores during the day.

Furthermore, almost all solar panels have a lifespan of at least 25 years, which makes them a worthwhile investment over the long term. This is especially true when you consider that the price of solar power has been dropping rapidly in recent years as manufacturers have developed new technologies that make it easier to manufacture and assemble solar panels than ever before.

The cost of residential solar power has fallen by as much as 30% in the past 5 years alone, and some experts predict that solar energy will be cost-competitive with conventional energy sources within the next decade. This won’t just save you money on your utility bills; it will also help reduce our dependence on fossil fuels and help limit our impact on the environment.

L2 / L3 / L4 type PV mounting structure made with import G.I Sheet 30 micron galvanized available in 12, 14 and 16 Gauge. The most poplar usage is 14 gauge PV mounting. However, due to rooftop layout and design, limited space availability  or due to shading problems customized PV mounting structure is being used. Customized PV mounting structure cost is based on how much material is used as well as quality of PV mounting

 

Flexible DC Wire – from Solar panel to inverter

The most useable application is 6mm wire but few installers use 4mm dc flexible wire with is not recommended if length is increased between solar panel array and on-grid inverter. up to 17 ampere per array 6mm dc flexible wire is the best choice

 

Earthing, Surge protection

Earthing is the most imported part also required by NEPRA and AEDB authorities to give approval/License for net metering (Green Meter). The ideal earthing should be up to water level depth. A pure cooper rope wire (without insulation) should be used. Wire thickness can be determined as per solar system size in Kilowatts. However, some installer only use 10 feet long copper rod only.

DC and AC earthing should be separate and minimum 10 feet distance should be maintained between both earth pits.

Earth pits should remain live by keeping it wet and resistance value must not increase >5 Ohms.

A surge arrestor should be installed on rooftop with higher altitude in comparison to PV module height.

 

Installation Related material (IRM a, b, c) 

Installation related material should be A Class quality. Since, customer like to get best available inverter in the market or best solar panel, installation materials such as pipe, duct, cable ties, MC4 connectors, DC fuses, SPD (Surge protection device) should be made by renowned brand.

a. Cable Ties

Cable ties should be made of pure nylon not ordinary plastic material and must be UV resistant. in other case cable ties will not last more than few months and all cable will be observed hanging in the air or lied down on the rooftop surface.

White cable ties are rated for indoor use only. for outdoor use only black nylon UV resistant cable ties are recommended

b. Pipe/Duct

Duct and pipe should be thick UPVC plastic material. As we assume solar system minimum life as 25 years.

c. MC4 Connectors

MC4 Pairs must be good quality and should not be remain loose while connecting male and female pairs. in other case they can caught fire, heating and energy loss. in some scenario loose connection can cause serious damage to the property.

 

Installation of Solar panels

Solar panels should be installed in shade free area of rooftop

Solar panel should be fixed properly, each nut, bolt fasted enough using torque wrench

solar panel should be 180 degree facing sought-ward, inclination of solar panel can vary from 5 degree to 40 degree depending on sun horizon as per area/terrain situation.

 

Installation of on-grid inverter

Mostly on-grid inverter are IP67/IP68 dust and splash resistant but direct UV rays of sun can fade and weaken the outer case of on-grid inverter. inverter must be installed in shady area where is proper air circulation available. If inverter is installed in air tight premises it can effect inverter performance and efficiency.

 

Online monitoring of solar system

Almost every on-grid inverter manufacture is offer built-in WIFI dongle and monitoring app  for cloud based online mentoring . Monitoring is available for Windows OS, Android and Apple IOS all platforms.

 

Net Metering / Green Meter / Feed Back to Grid License (up to 25KW domestic Solar system)

If you want to replace a Green Meter with conventional meter. It is a lengthy and tiring process. It take about 1.5 to 2.5 months.

as per New NEPRA policy a domestic user can apply for green meter once solar system is already installed.

 

Required documentation for green meter

  • Applicant CNIC Copy
  • Recent paid electricity bill Copy
  • Inverter Serial No.
  • Inverter Datasheet
  • Solar Panel Datasheet
  • Affidavit (Stamp Paper) PKR 50 or PKR 100
  • System layout diagram
  • Installer company invoice (company must have AEBD authorization)

important note: customer can install solar system @ 1.5 times factor of sanction load mentioned on his electricity bill. If sanction load is less than required demand, customer can write application to local division to increase it against a very nominal fee. estimated 1000 PKR/KW.

for example: if sanction load is 9KW customer can apply for 13.5KW solar system to feed back to grid.

 

Civil works

Civil work is necessary if rooftop is old or there is chance of seepage. concrete based pads should be at the point of anchor bolts on the rooftop. Also on open sided rooftops with no wall and in windy area concrete pad are very necessary.

 

Solar system Abnormal / Standby / Not Working

Check all three phases are live

Check Natural is not break

Check Solar panel array is connected to inverter

Check Phase sequence is proper (R-S-T) applicable to few inverter brands like infini 10KW design

Check AC Breaker is OK

Check DC Breaker or  fuse is OK

Check inverter screen or inverter app if it is showing warning or error code

Contact system installer

 

Maintenance of solar system

The only major maintenance of solar system is to keep your solar panels clean from dust layer.

Only water is required to wash the solar panel surface at least two time a week if there is not rain.

if solar panels are dusty, up to 30 percent energy production will be reduced.

How to extend battery life span (tips & tricks)

Tips & Tricks to Extend Battery Life span

 

  1. Always calibrate inverter when new batteries are installed as per provided datasheet from battery manufacturer

 

  1. Inverter and batteries should be placed where temperature must not exceed than 25°C. UPS location must be airy not suffocated.

 

  1. Do not deep discharge batteries. Maintain low cut-off 60% DOD (depth of discharge). Let remain 40% energy in battery.

 

  1. Maintain safe distance at-least 1.5 inch between each two batteries.

 

  1. If batteries stored are not being used, pass a charging cycle once in a month for Lead-Acid & Sealed Lead Acid MF (Maintenance Free) and Calcium batteries. Once in 6 month for DRY (AGM, GEL, VRLA) batteries, once in a year for Lithium batteries.

 

  1. If you have lithium battery always use compatible inverters or BMS (battery Management System).

 

  1. Keep a regular check on batteries if batteries are over-heating or seems swelled check inverter charge /discharge parameter.

 

  1. Use energy efficient appliances. Use LED bulb instead of conventional lights, use inverter AC or refrigerator available with maximum efficiency in the market. Energy efficient maybe available at bit high but it will use reduce electricity bill.
