Does my home have good conditions for installation?<\/h3>\n<p>It may seem simple, but many forget to assess:<\/p>\n<ul>\n<li>Roof orientation and tilt<\/li>\n<li>Shadows from buildings or trees<\/li>\n<li>Condition of the structure (tiles, waterproofing)<\/li>\n<\/ul>\n<p>An initial technical assessment helps determine whether the installation will be efficient or if adaptations are needed.<\/p>\n<h3>2. Do I know my energy consumption?<\/h3>\n<p>Before knowing how many panels you need, you should understand:<\/p>\n<ul>\n<li>Your average daily\/monthly consumption (in kWh)<\/li>\n<li>The times of day you consume the most (morning? night?)<\/li>\n<\/ul>\n<p>With this data, it\u2019s <strong>possible to correctly size<\/strong> the system \u2014 neither too much nor too little.<\/p>\n<h3>3. Is it worth including a battery?<\/h3>\n<p>A battery can <strong>increase self-consumption<\/strong> and allow you to use solar energy at night, but it comes with a slightly higher upfront cost.<\/p>\n<p><strong>Ideal for those who:<\/strong><\/p>\n<ul>\n<li>Spend many hours away from home during the day<\/li>\n<li>Want greater energy independence<\/li>\n<li>Live in areas with frequent power outages<\/li>\n<\/ul>\n<h3>4. Am I eligible for subsidies or tax benefits?<\/h3>\n<p>Currently, there are no active incentives from the Environmental Fund or reduced VAT for this type of installation.<\/p>\n<p>However, by installing the system with a <strong>certified company like Roteiro do Saber<\/strong>, your installation will be properly certified and eligible to apply as soon as new support lines or tax benefits are available.<\/p>\n<p>This ensures that you invest today in a safe, compliant system without missing the opportunity to benefit from future incentives.<\/p>\n<h3>5. Is the installation company certified?<\/h3>\n<p>Not all companies on the market meet the legal requirements to install self-consumption systems.<\/p>\n<p>Before accepting a proposal, check if the company:<\/p>\n<ul>\n<li>Has technicians certified by DGEG<\/li>\n<li>Offers <strong>online system monitoring<\/strong><\/li>\n<li>Provides <strong>maintenance and technical support<\/strong><\/li>\n<\/ul>\n<h3>6. How will the connection to the grid be made?<\/h3>\n<p>If you choose self-consumption with sale to the grid, it is necessary to:<\/p>\n<ul>\n<li>Submit a notification to DGEG<\/li>\n<li>Have a contract with an electricity supplier to sell excess energy<\/li>\n<li>Have a bidirectional meter<\/li>\n<\/ul>\n<p>It may seem complex, but with the <strong>right guidance<\/strong>, the entire process can be simplified.<\/p>\n<h3>7. How long until I start saving?<\/h3>\n<p>This depends on several factors:<\/p>\n<ul>\n<li>Total cost of installation<\/li>\n<li>Amount of support received<\/li>\n<li>Percentage of self-consumption<\/li>\n<\/ul>\n<p>On average, the <strong>return on investment ranges between 5 and 8 years<\/strong>, and panels last around 25 years.<\/p>\n<h2>Conclusion<\/h2>\n<p data-start=\"2896\" data-end=\"3017\">Installing solar panels is a worthwhile investment, but only if done with information, planning, and technical support.<\/p>\n<p data-start=\"3019\" data-end=\"3145\">At <strong data-start=\"3022\" data-end=\"3042\">Roteiro do Saber<\/strong>, we believe the right energy starts with the right question.
