When you install a solar energy system on your property, you save money on your electricity bills and protect yourself against rising electricity rates in the future. How much you can save depends on the utility rates and solar policies in your area, but going solar is a smart investment regardless of where you live.
Solar power, like other renewable energy resources, has many environmental and health benefits. Going solar reduces greenhouse gas emissions, which contribute to climate change, and also results in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems.
The easiest way to find out how much you pay for electricity (and how much electricity you use per month) is to take a look at your utility electricity bill.
Net metering is the system that utilities use to credit solar energy system owners for the electricity produced by their solar panels. With net metering, you only pay for the electricity that you use beyond what your solar panels can generate.
Studies have shown that homes with solar energy systems sell for more than homes without them. However, your property value will only increase if you own, rather than lease, your solar panel system. In most parts of the country, going solar will actually increase your property value more than a kitchen renovation.
Solar panels absorb the sun's energy throughout the day and convert it into direct current (DC) electricity. Most homes and businesses run on alternating current (AC) electricity, so the DC electricity is then passed through an inverter to convert it to usable AC electricity. At that point, you either use the electricity in your house or send it back to the electric grid.
The amount of power your solar energy system can generate is dependent on sunlight. As a result, your solar panels will produce slightly less energy when the weather is cloudy, and no energy at night. However, because of high electricity costs and financial incentives, solar is a smart decision even if you live in a cloudy city.
When you install solar panels on your property, you will still be connected to the grid. This allows you to draw from the grid when your system is not producing all of the power that you need, and send power back to the grid when you produce more than you use. It is possible to go off the grid with a solar energy system that includes battery storage, but it will cost significantly more and is unnecessary for the majority of homeowners.
Unless your solar energy system includes battery storage and you are fully off the grid, you will still receive a bill from your utility. However, you can dramatically reduce your bill, or even cut the amount you owe to $0, with a solar panel system that matches your energy use.
If your solar panel system is connected to the grid, it will shut off in the event of a blackout. This is to prevent emergency responders and electricity utility repair-people from being injured by your panels sending power back to the grid. However, there are certain inverters you can buy that provide backup power in a blackout when paired with a battery.
Solar panel systems are made of durable tempered glass and require little to no maintenance for the 25 to 35 years that they will generate power. In most cases, you don’t even need to clean your solar panels regularly. If something does happen, most equipment manufacturers include warranties, although warranty terms depend on the company.
Southerly-facing roofs with little to no shade and enough space to fit a solar panel system are ideal for installing solar. However, in many cases there are workarounds if your home doesn’t have the ideal solar roof
The size of your solar energy system will depend on how much electricity you use on a monthly basis, as well as the weather conditions where you live. Take a look at your past electricity bills and compare offers from licensed, pre-screened solar installers to determine the best system size for your needs.
Solar energy systems can last for 25 to 35 years, and it can be costly to remove and reinstall them if you need to replace your roof. If your roof needs maintenance in the near term, you should complete it before you finish your solar installation.

In general, solar panels are very durable and capable of withstanding snow, wind, and hail. The various components of your solar power system will need to be replaced at different times, but your system should continue to generate electricity for 25 to 35 years.
If you own your solar energy system, your solar house will sell at a premium: studies have shown that solar increases property values.
While every solar panel brand and product has unique specifications. Solar panels into three broad categories: Economy, Standard, and Premium. Premium panels perform the best, but have a higher price tag, while Economy panels are inexpensive but often less durable over time. Your decision about which category of solar panel to purchase depends on your priorities.
Power inverters convert the electricity your panels produce from direct current (DC) to alternating current (AC) power. There are three types of inverters: string/centralized inverters, microinverters, and power optimizers.
Solar power systems that include solar batteries, known as solar-plus-storage, are increasingly popular, but can be pricey. Luckily, batteries are not necessary for most solar homeowners. As long as you are connected to the grid, your system does not need a battery: excess power goes back into the grid, and you can draw from the grid if you need more electricity than your panels can generate.
The land required for a 1 MW power plant setup is around 4.5-5 acres for Crystalline technology and around 6.5-7.5 acres for Thin-Film technology. This is only a rough benchmark and may vary based on technology and efficiency of panels.
The useful life of a typical Solar Power plant is considered to be 25 years. This is the duration for which long-term PPAs are signed and financial models are built. However, Solar Power plants can run beyond 25 years while producing a lower output. Many Solar Panel manufacturers guarantee an output of 90% at the end of 10 years and 80% at the end of 25 years.
The usual benchmark for energy generated from a 1 MW Solar Power plant is considered as 1.5 Million units. This is only a benchmark and should not be considered as the actual output for a given location. The amount of actual energy generated from a Solar Power Plant in an year depends on both internal and external factors. External factors which are beyond the control of a Solar developer can include the following: Number of sunny days, Solar Irradiation, Day Temperatures, Air Mass.The output also depends on the following internal factors all of which are within the control of a Solar Developer: Plant Location Usage of Solar Tracking systems Quality of equipment used Workmanship of the EPC contractor O&M activities
The various modes under which a Solar Power plant can be setup depends on the specific requirement. All the following are valid modes and the costs for each kind of system varies based on various factors: Off-Grid Captive Consumption for domestic premises, Off-Grid Captive Consumption for commercial premises, Grid Connected (Net Metered) Captive Consumption for domestic premises, Grid Connected (Net Metered) Captive Consumption for commercial premises, Sale of Power generated to local Distribution Company (DISCOM), Sale of Power generated to 3rd Party consumer (Industry or Commercial entity)
Identifying the Solar Power plant size for your domestic or commercial premises depends on the following factors: Wattage of appliances to be run on Solar, Monthly energy consumption from these appliances, Energy Backup or Days of Autonomy required Roof space available for plant setup, Based on these factors, the power plant sizing can be accordingly done at your end.
Solar modules convert solar energy into electrical energy. The latter is stored in the battery. At dawn solar modules stop producing energy (no current), the controller realizes that it is dark and turns the light on. The light is turned off as soon as solar modules start producing energy in the morning.
All photinus luminaires operate for 75 to 100 hours with full batteries.The controller stops current supply to the LED as soon as the capacity of the battery gets lower than 30% (remaining capacity) in order to secure the battery from a deep discharge.
We suggest to clean the solar module and the LED module once a year. Battery has to be replaced every five years.LEDs have a life span of 12 years.
Average installation time is 20-30 minutes per luminaire.
The battery has to be replaced every five years. The reason therefore is, that the remaining capacity is too low to guarantee a satisfying operation (expecially in winter). Every technician is able to change the battery.
You can return your battery directly to photinus. The German foundation “Gemeinsames Rücknahmesystem Batterien” provides container to trader, townships and all public entities for the returning of batteries. This is free of charge. ERA-ELektroRecyclingAustria provides this service in Austria. 95% of all lead-gel batteries are recycled.
Battery: 5-8 years (depending on battery model), LED 12 years, PV-Modul 20-25 years, Pole & casing 30 years
According to official norms solar luminaires can illuminate minor and residential roads at less than 30 km/h. These are especially the S-classes according to DIN EN13201. In addition, all walk- and bicyle ways can be illuminated according to official norms.
If needed, motion sensors can be applied to all photinus luminaires in order to turn the luminaires on and off. Please consider that the range of available motion sensors is limited to 10 meters.
A decade of expercience with solar lighting tought us, that we need a relation of 10:1 between the PV performance and the LED performance. One can ensure operation in Middle Europe during winter only under these circumstances. This means: 300W PV performance equals 30W lighting performance Photinus solutions range between 3-30 W lighting performance and between some 300 – 3000 lm luminous flux. Be aware, that some competitor use values of summer operation in their data sheets.
Photinus energy towers are designed vertically, hence it is not possible that snow remains on the solar modules. Due to the increased total radiation through reflection the radiation to the solar luminaire is even higher at snowy conditions.
Yes. Solar luminaries already work above the 48. latitude for a number of years. Photinus luminaires operate successfully in Moscow (55. latitude). Nevertheless, it is not possible to use any luminaire at any place on earth.
Luminaires are either fixed by using a screw fundament (Krinner) or by using a traditional concrete pipe.

KP Smart Energy is not competing with the traditional, on grid streetlight; it offers rather a valuable endorsement and different solution. We take it as our duty to investigate whether installations of lighting points make ecological and economic sense or not.
