- What is the value of M2M technology? Give two examples.Under insolation conditions of 500 W/m2 (direct sunlight), and 10% solar cell efficiency (defined as the ratio of electrical output power to incident solar power), calculate the area required for a photovoltaic (solar cell) array capable of running the above vehicle at half power. Note: The vehicle is driven by a motor of 40 hp.A barangay power station supplies 60kW to a load over 2,500ft, 100 mm², two conductors copper feeder. The resistance of which is 0.0078 ohm per 1,000 ft the bus bar voltage is maintained constant at 600V. Determine the load current.
- A family of five is planning to install solar panels on the roof of their home to help reduce the cost of electricity and save energy to help the environment. The family plans to install 10 panels, each with a power rating 600W. On average, a solar panel can produce electricity for 4.5 hours daily. Each person in the family uses electrical energy at an average rate of 2kilowatt-hour per day. Will they still need to buy electricity from an electrical energy supplier? Explain your reasoning.For the solar cell attached, find the relative maximum power output for series resistance, Rs of 0 ohms and 5 ohms.A farm has a monthly consumption of 400 kWh, where all energy consumed is generated through of biogas. Consider that 1m3 of biogas is equivalent to 1.4 kWh. In the calculation, consider that the raw material of the biodigester will consist of swine manure that produces 4 kg of manure each, with retention time in the biodigester for 45 days. What is the daily biogas consumption to serve this residence and how much waste is needed daily?

Find the total energy available in kWh if the overall efficiency is 70% note: please solve that clear answer.How much electrical energy can be produced in a year by a conventional electrical power plant of 100 MW if the power plant functioned 80% of the time (the rest being spent on maintenance). If one small solar power plant with average W = 0.15 MWh/m2 per year is going to be built to replace that conventional electrical power plant, calculate how much area in km2 that needed?e newly appointed Government of a small island, depend on the import of fossil fuels to produce electricity, has the desire to invest in one or two renewable energy technologies. The advantage of the island is the number of different renewable energy potentials. The cost of electricity on the island is $0.39 kWh. 1) Using solar radiation photovoltaic technologies, it was estimated that 500 rooftops, with a total surface area of 456 000 m2 , will be available to install the photovoltaic panels. Assume that the solar panels actually cover 90% of the available surface area. Given, the size of a standard photovoltaic cell is 156 mm by 156 mm and for a silicon photovoltaic cell, each PV cell produces a current of 2.5 A at a voltage of 0.5 V. The average daily irradiance for the island is 185 W/m2 . Assume the initial capacity expenditure evaluated on a year basis of the photovoltaic system, that covers, 90% of the available surface area is US $600 000 and the annual operating cost is US $5…
