So the electricity generation from the alternative sources has become the crying need for Nepal. Nepal is blessed with renewable energy resources and the availability of alternative energy creates opportunities for utilization in power sector. Among different renewable energy sources like solar, wind, biomass and others, the abundant availability of solar energy makes it the most promising one for Nepal.
Nepal is situated 28 degrees 00' N and 84 degrees 00' E which is an ideal location for abundant solar radiation.
The daily average solar radiation in Nepal is 3. In view of the dispersion of localities, the low demand, the cost of production, transmission and especially distribution of electricity would be prohibitively expensive for these regions. Therefore renewable energy based off grid electrification can be an alternate option for providing electricity in large remote and rural areas of Nepal. However, there are inconveniences associated with these systems as follows: 1.
Due to the steady increase in the price of fuel for the past few years, most of these systems have become expensive leading to an increase in the price of water for domestic consumption and irrigation. Most of these systems require high maintenance since they have many moving parts. There is low grid power coverage in the country; therefore grid powered pump cannot be used in most of the parts in the country.
To overcome the inconveniences, there is a need to design and construct a solar powered water pumping system. Due to geographical position, Nepal has ample sunshine through the year which makes it ideal location for utilization of solar energy. Small farms, villages, and animal herds in developing countries require hydraulic output power of less than a kilowatt. Many of these potential users are too far from an electrical grid to economically tap that source of power, and engine-driven pumping tends to be prohibitively expensive as well as unreliable due to the high cost of purchased fuel and insufficient maintenance and repair capabilities.
Though the installation cost of solar powered pumping system is more than that of gas, diesel, or propane-powered generator based pumping system but it requires far less maintenance cost.
However by comparing installation costs including labor , fuel costs and maintenance costs over 10 years with other conventional fuel based pumping system, the solar PV water pumping system can be a suitable alternate option. This system has the added advantage of storing water for use when the sun is not shining, eliminating the need for battery, simplicity and reducing overall system costs.
Initial survey and planning 2. Site visit and case study 3. Collection of information and data 1. Initial survey and planning The initial survey is about pumping techniques and other systems related to our project. Any work without planning is like story without any end.
Planning is a very necessary and important step before starting a project. So we planned about the works and divided the works according to time basis. Detailed planning is shown in the Gantt chart in page 8. Site visit and case study Our proposed project site is Bhandara V. C, ward number, Chitwan. We will be visiting the site and study their existing pumping technique and their problem.
We shall collect information about the problems faced at the site. From site visit we will be clear about the objective of the project. Collection of information and data Information and data relevant to project work were collected in following ways: a Literature Survey b Market Survey a. Based on the review of literature, the study is designed based on conceptual framework. Upon finalization of framework an inception report is prepared and presented to the advisor. Market Survey It is to obtain information about the instruments regarding price, rating, availability, functions, performance, alternatives etc.
The electric current produced by PV panel during daylight hours charges the battery and the battery in turn supply power to the pump anytime whenever the water is needed.
To determine whether the tank is full or empty level sensor is used. The use of battery spreads the pumping over a longer period of time by providing a steady operating voltage to the DC motor of the pump. Feasibility Study 2. System Specification 3.

The battery will add charger is: 1 robust and reliable for solar battery charging NiMH batteries, 2 compact, and 3 that the addition of MPPT [] inside the charger could maximize output battery bank during varying atmospheric conditions.
While it may seen instinctive to incorporate several solar panels in order to harvest more energy, this proof of concept project … View and Download Projecta IDC25 user manual online. IDC25 Battery Charger pdf manual download. The post explains a simple solar battery charger circuit using the IC LM which can be built and installed by even a layman for achieving the intended results. The main property of this device to convert solar project even more fun. It is a subtle indication of cloud activity.
It audibly indicates the switching action of the charger. The battery charge rates are selected with switches for fast or slow. Battery 6 has a potentiometer to adjust the rate of charge. This is handy for testing or for heavier duty batteries.
Keep in mind that the output of all charge circuits together must not exceed an 85 W solar energy battery charger and a 25 W LED lamp driver. During the daytime the controller preserves the electricity energy gathered by the solar module PV module , then stores it in the battery.
In the evening the controller uses the battery energy to power the LED streetlight. When the battery runs out of power after several rainy days, the controller enables the external offline Designing a Solar Cell Battery Charger. The market for portable solar powered electronic devices continues to grow as consumers look for ways to reduce energy consumption and spend more time outdoors. Only a few components are required and construction is very simple making this a perfect first renewable energy project.
It combines high-quality power electronic components with advanced controls to seamlessly transfer energy from the sun to batteries.
Available in PWM and MPPT models and featuring advanced communication options including optional The project is about to develop and fabricate the circuit that can charge the lead acid battery during day time by using solar as the source. Lead-acid batteries are finding considerable use as both primary and backup power sources.
What is the best portable solar charger? Portable solar battery chargers are perfect for maintaining and extending the life of 12V power systems for cars, trucks, tractors, motorcycles, boats, ATVs, RVs, and … solar battery charger free download.
