    How to calculate electrical energy after installing solar panels

    How to calculate electric energy after installing solar panels The contracted power represents a fixed part that we pay monthly in our electricity bill. It is represented in kilowatts (kW) and measures the quantity of electrical devices that can be used simultaneously in the residence without interruption of the supply or tripping of two cables (activation of the ICP). All this defines a regulated cost that is applied to cover the costs generated by the electrical system, known as an access portage attributed to the supply point. Therefore, the lower the consumption needs of the vehicle, the less it will be necessary to pay. By installing solar panels we reduce the electricity consumption of the electrical network, so we achieve reductions in the fixed part of our electricity consumption through the reduction of the contracted electrical energy. See how. Aspects to be considered are the methods of calculating electrical energy. Different factors must be taken into consideration in the calculation of the electrical power necessary for a vehicle, the most important being: – The consumption in kW/h of all electrical devices and devices, and How many are used simultaneously – The needs of use of light and schedules of the inhabitants of the house – The size of the vehicle, represented in square meters Next, to carry out the calculation, different methodologies can be used, such as the following: – Carrying out a study free power. For example, Selectra estimates free of charge the necessary power of the house in accordance with the client's needs and supply conditions. – Hire an authorized electrician, who comes to the residence to determine the characteristics of the supply and calculate the most adequate power – Using an online power calculator, which allows you to know an estimate of the power that must be contracted, providing the characteristics of the house, two appliances and two inhabitants Steps to change the contracted power To change the contracted power we will have to contact our electric energy supplier with the following documentation: – Details of the contract holder: name, surname, identification document and contact – Kilowatts of electric energy current – ​​Kilowatts of power that you wish to contract – Postal information of the vehicle and CUPS code of the electricity The process will come into effect within a maximum period of 20 days and can be carried out in person at our desks, it is recommended that the use of telephone or online channels for more celeridade. What is the price for altering the contracted electrical energy? The price of alteration of the contracted power in a room constitutes a set of regulated direitos for the distributor of the zone. It represents a single payment that must be paid on the next electricity bill, once the energy change has occurred. To reduce the contracted power you will have to pay exclusively to the connection tax, which does not depend on the number of kilowatts reduced, therefore you will always have a cost of €9,04, plus VAT.

    Save by combining aerothermal energy and solar panels

    Save by combining aerothermal energy and solar panels Currently, aerothermal energy has positioned itself as one of the systems with the highest performance, this is due to its ability to convert 1 kW of light consumed into 4 kW of heat energy. Therefore, while its energy efficiency is 400%, the user uses only 25% of that heat energy produced. Furthermore, if we combine this system with the installation of solar panels, the savings will be total, below we explain why. Operation of aerothermal energy and solar panels Aerothermal energy operates by transferring energy from the outside of the room to the inside. That is, in summer it obtains heat from the outside air, passes it through an internal liquid with refrigerant liquid and, through air conditioning, transmits it to the room. This makes it a comprehensive air conditioning system, as it is capable of producing heating in winter, heat in summer and hot water throughout the year. In each case, it will be necessary to choose the thermal emitter intended for this. For example, underfloor heating is a very wise decision, as it allows the diffusion of cold or heat depending on the needs of the consumer and distributes the necessary energy evenly throughout the room. Its installation is very simple and economical, it consists of a set of polyethylene pipes installed under the ground, which do not require specific maintenance. On the other hand, solar panels convert solar radiation into electrical energy, allowing the consumption needs of a home to be supplied completely free of charge during the more than 25 years of useful life of the system. Advantages of combining the aerothermal system with self-consumption It should be noted that an installation of solar panels alone is capable of reducing electricity consumption by up to 70%. But, if we also combine it with aerothermal energy, the supply will be capable of consuming free energy for air conditioning, which represents 80% of the total bill in winter, and electricity costs can be completely eliminated. To give us an idea, in about 30 years, you can save approximately €45.000, if we compare it with other heat sources such as gas or diesel. Although in some cases, the initial outlay required to carry out both installations may be high, it is a cost that is amortized in less than 6 years and, from then on, the home will be able to consume energy completely free of charge. Cost of the aerothermal and solar panel project The cost of installing an aerothermal system varies between €8.000 and €25.000 depending on factors such as the size of the property, the electrical power contracted for supply or the output devices used. they are going to employ. However, the price reduces as the size of the installation increases.

    Budget to install solar panels in your home

    Budget to install solar panels in your home. Thinking about alternatives to reduce the electricity bill that has not stopped growing in recent months? It is a good time to opt for solar self-consumption to reduce this expense, since you can produce your own energy and also combat pollution. Solar panels are an increasingly present solution in single-family homes, since they are capable of converting solar radiation into the electrical energy that the supply needs for its operation. How much does it cost to install solar panels in a home? Installing solar panels, although it involves a high initial financial outlay, is an investment that can be amortized in the medium term and highly profitable. First of all, it is advisable to request a quote for solar panels from several installation companies and compare them to choose which one is the most appropriate. Some of the aspects that can influence the total cost are the following: – The type of home: whether it is a single-family home, semi-detached, an apartment... – The use that will be made of the facility: primary home or second home – The hours of sunshine in the province – The price of the electricity bill in the last 12 months – The CUPS number of electricity The average price of a photovoltaic solar panel system is between €600 and €800 per square meter To give us an idea, it will be around €4.500 including equipment and labor. Budgets for the installation of solar panels Generally, those interested in this type of installation receive two types of budgets from the installation company, the first is indicative and the second is the definitive one and involves hiring the service Online budget: It is a form by which the calculation of solar panels, the cost of installation and the estimate of energy savings are estimated. It does not have any type of validity Final estimate: It is obtained once the installation company visits the property. This document includes all the technical aspects of the work: the study of energy savings, the payment plan and the price breakdown of the photovoltaic components. Your acceptance starts the process. How many solar panels do I need in my home? One of the most important procedures for starting up the photovoltaic installation is to calculate how many solar panels I need. This process is known as sizing the installation and, to carry it out, it is necessary to have the annual consumption in kWh of the home, that is, its electricity bills from the previous 12 months. …

    How to choose the best compensation for your photovoltaic surpluses

    How to choose the best compensation for your photovoltaic surpluses In Spain, the sale or compensation of surplus unconsumed energy is allowed for all those users who have an installation of solar panels in their supply. To benefit from this compensation, it is necessary that the system remains connected to the electrical grid and, in addition, the following requirements must be met: – That the supply does not exceed 100 kW of contracted power – Have a bidirectional meter – That the owner cannot profit from it. The price received for the surplus will depend on what was agreed with the electricity company in the contract, therefore, below we are going to give you the keys so that you can locate the most beneficial rate for your property. Free or regulated electricity marketer The first step to achieve the maximum savings provided by surplus energy is to carry out a comparison to choose between the regulated or free tariff. Remember to take into account the price you will pay for electricity when the solar panels do not produce electricity due to lack of radiation. Regulated tariff or PVPC The reference marketers are 8 and operate exclusively with a tariff called PVPC (Voluntary Price for Small Consumers), whose prices are the following: – The price of the kWh of electricity that we consume is set based on the supply and market demand and is semi-regulated by the Government, therefore, it has different prices every day and every hour – The price of the energy surplus is valued at the average hourly price, which is currently around €0,05 and €0,06/ kWh Light consumption is experiencing large increases this year and, consequently, so is the price at which surpluses are compensated. Free rates There are more than 300 free marketers and they establish their rates and contract conditions independently of each other. This means that both the price of the kWh of electricity consumed, as well as that of the surplus energy, is valued based on the rate that we decide to contract, allowing us to obtain very advantageous offers and promotions. What is the best rate with compensation for surpluses If you have just installed solar panels in your home, or are thinking about doing so, and want to opt for the self-consumption modality with surpluses, we recommend making a comparison between the different offers From the market. You should know that choosing one or the other is a completely personalized process, depending not only on the price, but also on the consumption habits and needs of the property. Therefore, what is good for one may not be the most beneficial for another, and in this sense, it is vital to seek advice from a professional. Below we indicate the most important aspects to take into account when choosing between the best electricity rates: – The price per kilowatt hour of the energy consumed – The price per kilowatt hour…

    Consumption study prior to the installation of solar panels

    Consumption study prior to the installation of solar panels When we start a photovoltaic project in our property, it is essential to carry out a thorough prior consumption study in order to obtain the greatest profitability of our solar panels, as it will directly impact the the results are optimal and real. To start this analysis, it is vital to know and understand all the sections that make up our electricity bill, so it is essential to have the receipts for the last 12 months or, failing that, the most recent ones. Below we indicate the keys to extracting the data correctly and the most important aspects that we must take into account. Energy consumption of the property The energy consumed represents a variable term in our electricity bill, so the kWh will increase or decrease in each billing period. This consumption will allow us to analyze the energy needs of the property, that is, if it requires more electricity at night, in the morning, or if it is regular throughout the day. This will choose the number of solar panels necessary to correctly size your installation and production. For example, if the property requires more electricity at night than during the day, a lithium battery will have to be incorporated into the installation to store the energy produced by the panels during the day for consumption at night. Electrical power contracted in the property The electrical power contracted represents a fixed part that we pay every period in our electricity bill, so it is completely independent of energy consumption. It is expressed in kW and measures the amount of electrical appliances that can be used at at the same time in the property without a power outage or the leads tripping. It is a very relevant piece of information when it comes to sizing our solar panels, since it allows us to know the electrical capacity from which we start in order to be able to size the photovoltaic project based on it. Cost of the property's electricity bill Finally, we will have to check the price that the consumer pays for the property's electricity in order to realistically estimate the return on the photovoltaic investment. It is advisable to first identify if we have a regulated or free contract, as it will allow us to streamline management to a greater extent. Regulated contract If the contract is regulated, we will have the PVPC rate, whose price is supervised by the Government every day and every hour based on the existing supply and demand in the wholesale electricity market. In this case, when carrying out the consumption study it will be necessary to consult the price of electricity today in the BOE, in addition to the average price per kWh paid in recent months. Being such an unstable market, we will obtain a less accurate calculation of the return on investment. Free contract If our electricity contract is free, it will be very easy to locate the cost...
